  • How can I determine if an image has loaded, using Javascript/jQuery?

    - by Kip
    I'm writing some Javascript to resize the large image to fit into the user's browser window. (I don't control the size of the source images unfortunately.) So something like this would be in the HTML: <img id="photo" src="a_really_big_file.jpg" alt="this is some alt text" title="this is some title text" /> Is there a way for me to determine if the src image in an img tag has been downloaded? I need this because I'm running into a problem if $(document).ready() is executed before the browser has loaded the image. $("#photo").width() and $("#photo").height() will return the size of the placeholder (the alt text). In my case this is something like 134 x 20. Right now I'm just checking if the photo's height is less than 150, and assuming that if so it is just alt text. But this is quite a hack, and it would break if a photo is less than 150 pixels tall (not likely in my particular case), or if the alt text is more than 150 pixels tall (could possibly happen on a small browser window). Edit: For anyone wanting to see the code: $(function() { var REAL_WIDTH = $("#photo").width(); var REAL_HEIGHT = $("#photo").height(); $(window).resize(adjust_photo_size); adjust_photo_size(); function adjust_photo_size() { if(REAL_HEIGHT < 150) { REAL_WIDTH = $("#photo").width(); REAL_HEIGHT = $("#photo").height(); if(REAL_HEIGHT < 150) { //image not loaded.. try again in a quarter-second setTimeout(adjust_photo_size, 250); return; } } var new_width = . . . ; var new_height = . . . ; $("#photo").width(Math.round(new_width)); $("#photo").height(Math.round(new_height)); } }); Update: Thanks for the suggestions. There is a risk of the event not being fired if I set a callback for the $("#photo").load event, so I have defined an onLoad event directly on the image tag. For the record, here is the code I ended up going with: <img id="photo" onload="photoLoaded();" src="a_really_big_file.jpg" alt="this is some alt text" title="this is some title text" /> Then in Javascript: //This must be outside $() because it may get called first var isPhotoLoaded = false; function photoLoaded() { isPhotoLoaded = true; } $(function() { //Hides scrollbars, so we can resize properly. Set with JS instead of // CSS so that page doesn't break with JS disabled. $("body").css("overflow", "hidden"); var REAL_WIDTH = -1; var REAL_HEIGHT = -1; $(window).resize(adjust_photo_size); adjust_photo_size(); function adjust_photo_size() { if(!isPhotoLoaded) { //image not loaded.. try again in a quarter-second setTimeout(adjust_photo_size, 250); return; } else if(REAL_WIDTH < 0) { //first time in this function since photo loaded REAL_WIDTH = $("#photo").width(); REAL_HEIGHT = $("#photo").height(); } var new_width = . . . ; var new_height = . . . ; $("#photo").width(Math.round(new_width)); $("#photo").height(Math.round(new_height)); } });

  • Does C# have an equivalent to JavaScript's encodeURIComponent()?

    - by travis
    In JavaScript: encodeURIComponent("©v") == "%C2%A9%E2%88%9A" Is there an equivalent for C# applications? For escaping HTML characters I used: txtOut.Text = Regex.Replace(txtIn.Text, @"[\u0080-\uFFFF]", m => @"&#" + ((int)m.Value[0]).ToString() + ";"); But I'm not sure how to convert the match to the correct hexadecimal format that JS uses. For example this code: txtOut.Text = Regex.Replace(txtIn.Text, @"[\u0080-\uFFFF]", m => @"%" + String.Format("{0:x}", ((int)m.Value[0]))); Returns "%a9%221a" for "©v" instead of "%C2%A9%E2%88%9A". It looks like I need to split the string up into bytes or something. Edit: This is for a windows app, the only items available in System.Web are: AspNetHostingPermission, AspNetHostingPermissionAttribute, and AspNetHostingPermissionLevel.

  • How can I center something if I don't know ahead of time what the width is?

    - by zeckdude
    I am trying to center a paragraph tag with some text in it within a div, but I can't seem to center it using margin: 0 auto without having to specify a fixed width for the paragraph. I don't want to specify a fixed width, because I will have dynamic text coming into the paragraph tag and it will always be a different width based on how much text it is. Does anyone know how I can center the paragraph tag within the div without having to specify a fixed width for the paragraph or without using tables?

  • How do I process a jQuery SVG group event in a single handler?

    - by rmflow
    I'm trying to draw a button using jQuery SVG, the button is a filled rect and the text is placed on top of the rect. Rect and text are grouped and I want to control the mouseover/mouseout events. The problem is: mouseover/mouseout events are triggered separately for every element of the group. Is it possible to make a single event handler for entire group? Here is an example: gClear = svg.group(); btClear = svg.rect(gClear, 10, 10, 100, h-20, 5 ,5, attrs); txtClear = svg.text(gClear, 35, 30, "Clear", {fontFamily: "Verdana", fontWeight: "bold", fontSize: "16px"}); $(gClear, svg.root()).bind("mouseover", function() { $(btClear).animate({svgFill: '#adf'}, 100); }).bind("mouseout", function() { $(btClear).animate({svgFill: '#fff'}, 100); }) When I move the mouse inside the rect the events mouseover/mouseout are triggered. Can I make "text" events transparent or can I have a single event handler for the group?

Am I doing something wrong?

  • How can I access and modify objects inside frames with AS3 in a permanent way?

    - by curro
    I have a MovieClip symbol created with flash in a fla file library. There is a textfield in frame one of this movieclip's timeline . There is another frame in the movieclip timeline. There is a custon class definition for this symbol. It is a flipping card in a memory game. I access the textfield by going to frame 2 (gotoAndStop(2)) and setting the textfield's text property ( this.field.text = "hello" ). However if I go to frame 1 and then return to frame 2, the text becomes the original one in the library's symbol. I have to modify the text propery again in a showFace method I've written. Besides, I cannot pass parameters in the constructor because it is a symbol in the library and that would give errors. I find this behaviour of flash extremely weird. Is there a way I can set properties inside frames permanently? Thank you

  • SQL indexes for "not equal" searches

    - by bortzmeyer
    The SQL index allows to find quickly a string which matches my query. Now, I have to search in a big table the strings which do not match. Of course, the normal index does not help and I have to do a slow sequential scan: essais=> \d phone_idx Index "public.phone_idx" Column | Type --------+------ phone | text btree, for table "public.phonespersons" essais=> EXPLAIN SELECT person FROM PhonesPersons WHERE phone = '+33 1234567'; QUERY PLAN ------------------------------------------------------------------------------- Index Scan using phone_idx on phonespersons (cost=0.00..8.41 rows=1 width=4) Index Cond: (phone = '+33 1234567'::text) (2 rows) essais=> EXPLAIN SELECT person FROM PhonesPersons WHERE phone != '+33 1234567'; QUERY PLAN ---------------------------------------------------------------------- Seq Scan on phonespersons (cost=0.00..18621.00 rows=999999 width=4) Filter: (phone <> '+33 1234567'::text) (2 rows) I understand (see Mark Byers' very good explanations) that PostgreSQL can decide not to use an index when it sees that a sequential scan would be faster (for instance if almost all the tuples match). But, here, "not equal" searches are really slower. Any way to make these "is not equal to" searches faster? Here is another example, to address Mark Byers' excellent remarks. The index is used for the '=' query (which returns the vast majority of tuples) but not for the '!=' query: essais=> EXPLAIN ANALYZE SELECT person FROM EmailsPersons WHERE tld(email) = 'fr'; QUERY PLAN ------------------------------------------------------------------------------------------------------------------------------------ Index Scan using tld_idx on emailspersons (cost=0.25..4010.79 rows=97033 width=4) (actual time=0.137..261.123 rows=97110 loops=1) Index Cond: (tld(email) = 'fr'::text) Total runtime: 444.800 ms (3 rows) essais=> EXPLAIN ANALYZE SELECT person FROM EmailsPersons WHERE tld(email) != 'fr'; QUERY PLAN -------------------------------------------------------------------------------------------------------------------- Seq Scan on emailspersons (cost=0.00..27129.00 rows=2967 width=4) (actual time=1.004..1031.224 rows=2890 loops=1) Filter: (tld(email) <> 'fr'::text) Total runtime: 1037.278 ms (3 rows) DBMS is PostgreSQL 8.3 (but I can upgrade to 8.4).

  • Flex/Air/AS3 Selecting and Populating a unFocused tab.

    I'm having a problem displaying data from a function to text box within a tab. If you run the code and click "Select Tab 2 and Fill..."

  • Alternative for table mark-up in ASP.NET not working properly

    - by yetanothercoder
    Using Visual WebDeveloper 2010 Express and ASP.NET 4.0 Don't know whether its relevant but the whole thing is in a ContentPlaceHolder and inside an UpdatePanel. To avoid using the old table tr td model, I have created a simple form like this <div class="admin-form"> <asp:Label ID="UserNameLabel" runat="server" CssClass="form-label" Text="User Name" /> <asp:TextBox ID="UserNameText" runat="server" Width="200px"/> <br /> <asp:Label ID="PasswordLabel" runat="server" CssClass="form-label" Text="Password" /> <asp:TextBox ID="PasswordText" runat="server" TextMode="Password" Width="200px"/> <br /> <asp:Label ID="ConfirmPasswordLabel" runat="server" CssClass="form-label" Text="Confirm Password" /> <asp:TextBox ID="ConfirmPasswordText" runat="server" TextMode="Password" Width="200px"/> <br /> <asp:Label ID="EmailLabel" runat="server" CssClass="form-label" Text="Email" /> <asp:TextBox ID="EmailText" runat="server" Width="200px"/> <br /> <br /> <br /> <span class="form-label"></span> <asp:Button ID="CreateUserButton" runat="server" CssClass="button blue" Text="Create New User"/> </div> And the CSS .form-label { width: 300px !important; } This renders incorrectly as I would like to have all textboxes vertically lined after taking 300px. What is wrong? P.S: I cannot use HTML Controls like label as I have resx for globalization

  • How do I unhide a CFDIV that has dynamic content with AJAX binding itself?

    - by Eric Belair
    I have the following CFSELECT tags that are used to populate a text input: <cfselect id="this" name="this" bind="cfc:Data.getThis()" bindonload="true" /> <cfselect id="that" name="that" bind="cfc:Data.getThat({p1})" /> <cfselect id="theOther" name="theOther" bind="cfc:Data.getTheOther({p1}, {p2})" /> The text input is the only value that needs to be submitted in a form: <cfform name="addItem" method="post" action="somepage.cfm"> <cfinput type="text" id="item" name="item" bind="cfc:Data.getResult({this}, {that}, {theOther})" /><br /> <cfinput type="submit" name="addButton" value="Add Item" /> </cfform> I want the form and it's contents to be visible only when all three selections have been made, and there is a value for the text input. What is the best way to do this? I'm assuming some use of CFDIV is the best way, but I'm not sure how to load the dynamic content (the CFINPUTs) this way.

  • Ignoring a character along with word boundary in regex

    - by DavidP6
    I am using gsub in Ruby to make a word within text bold. I am using a word boundary so as to not make letters within other words bold, but am finding that this ignores words that have a quote after them. For example: text.gsub(/#{word}\b/i, "<b>#{word}</b>") text = "I said, 'look out below'" word = below In this case the word below is not made bold. Is there any way to ignore certain characters along with a word boundary?

  • simple XML question for perl - how to retrieve specific elements

    - by Jeff
    I'm trying to figure out how to loop through XML but I've read a lot and I'm still getting stuck. Here's the info: I'm using the wordnik api to retrieve XML with XML::Simple: $content = get($url); $r = $xml->XMLin("$content"); The actual XML looks like this: <definitions> - <definition sequence="0" id="0"> - <text> To withdraw one's support or help from, especially in spite of duty, allegiance, or responsibility; desert: abandon a friend in trouble. </text> <headword>abandon</headword> <partOfSpeech>verb-transitive</partOfSpeech> </definition> - <definition sequence="1" id="0"> - <text> To give up by leaving or ceasing to operate or inhabit, especially as a result of danger or other impending threat: abandoned the ship. </text> <headword>abandon</headword> <partOfSpeech>verb-transitive</partOfSpeech> </definition> - <definition sequence="2" id="0"> - <text> To surrender one's claim to, right to, or interest in; give up entirely. See Synonyms at relinquish. </text> <headword>abandon</headword> <partOfSpeech>verb-transitive</partOfSpeech> </definition> - <definition sequence="3" id="0"> ... What I want is simply the FIRST definition's part of speech. I'm using this code but it's getting the LAST definition's POS: if($r->{definition}->{0}->{partOfSpeech}) { $pos = $r->{definition}->{0}->{partOfSpeech}; } else { $pos = $r->{definition}->{partOfSpeech}; } I am pretty embarrassed by this since I know there's an obviously better way to do it. I would love to get something as simple as this working so I could more generally loop through the elements. BUt it just isn't working for me (no idea what to reference). I've tried many variations of the following - this is just my last attempt: while (my ($k, $v) = each %{$r->{definitions}->{definition}[0]->{sequence}->{partOfSpeech}}) { $v =~ s/'/'"'"'/g; $v = "'$v'"; print "export $k=$v\n"; } Lastly, when I do "print Dumper($r)" it gives me this: $VAR1 = { 'definition' => { '0' => { 'partOfSpeech' => 'noun', 'sequence' => '6', 'text' => 'A complete surrender of inhibitions.', 'headword' => 'abandon' } } }; (And that "noun" you see is the last (6th) definition/partofspeech element).
