  • JQuery ready event and its shortcut

    - by Sarfraz
    Hello, In most of the videos, I see expert JQuery developers writing complete code for the ready event eg: $(document).ready(function(){ //..... }); rather than its shortcut: $(function(){ //..... }); Is there any particular down side to using shortcut method?

  • How do I hide an HTML element before the page loads

    - by Robert
    I have some JQuery code that shows or hides a div. $("div#extraControls").show(); // OR .hide() I initially want the div to be not visible so I used: $(document).ready(function() { $("div#extraControls").hide(); }); However, on the browser, the content loads visible for a second before disappearing, which is not what I want. How do I set the hide the element before the page loads whilst keeping the ability to show hide it dynamically with a script?

  • What are supported clients for an asp.net webpage?

    - by Maestro1024
    What are supported clients for an asp.net web page? I am trying to document an asp.net website and I am unsure what I should say as far as client support. Are there limitations for asp.net as far as browsers? I have used IE and Firefox does it not work with some of the other browsers (chrome or safari)? Should I say the client is limited to any specific OS (I would expect it to work with a Mac or a Linux box)?

  • JQuery, Load() contents with plugins

    - by Galas
    I know this is not a completely new question, but none of the answers solved my problem... I have built a little menu that uses load() to load image galleries (as external html files) into a specified div ("content"). The said galleries make use of a JQuery plugin (SlideJS). Now I know that load() does not work for script tags and that I need to use $.getscript in the callback function in order to run the scripts, but it does not work. I have two .js files that need to be loaded: one is the plugin itself and another one is a smaller script with a preloader and the animations for the captions. I can't seem to merge them together; if I put them into the same document, the script won't run. So I tried just using $.getscript to load the two files. I tried using two callbacks as suggested in other answer (I know it's not ideal...): $("#proposal").click(function(){ $(this).addClass('selected'); $("a:not(:#proposal)").removeClass('selected'); $("#content").load("works/proposal/proposal.html", function(){ $.getScript("js/slide.js", function (){ $.getScript("js/slidepage.js"); }); }); }); and I tried a variable (read about it in some other faq, not sure if the syntax is correct) $("#proposal").click(function(){ $(this).addClass('selected'); $("a:not(:#proposal)").removeClass('selected'); $("#content").load("works/proposal/proposal.html", function(){ var scripts = ['js/slide.js','js/slidepage.js']; $.getScript(scripts); }); }); So none of these work. What am I doing wrong? I'm just starting on jquery and my js knowledge is very limited. Should I just merge the two .js files together using minify or something? One of them is already minified, but I've tried with a non-minified version and it does not work either. Can anyone suggest any other solution around this problem? I thought of just having the div embedded in the main document and just showing it on click, but I'll have at least 4 galleries with about 8 to 10 images each... its a lot of images to load in the main page, so I don't think its the best way. if you need me to post any more code, please ask! Thanks in advance for all your help!

  • Determining the order of DOM elements

    - by sonofdelphi
    Given two DOM elements, say a and b, how can we determine which comes first in the document? I'm implementing drag and drop for a set of elements. And the elements can be selected in any order, but when they are dragged, these elements need to be moved in the "correct" order.

  • Autopopulate from Select box from database

    - by Chris Spalton
    hope you can help, please forgive any poor coding or anytihng, I'm new to this and just hacking my way through to get things to work. That said, on one of my projects I have this code, which successfully populates the dropdown from a database when the page is loaded: <select name="Region" id="Region"> <option value="">-- Select Region --</option> <?php $region=$POST['Region']; if ($region); { $regionquery = "SELECT DISTINCT REGION FROM Sales_Execs "; $regionresult = mysql_query($regionquery); while($row = mysql_fetch_array($regionresult)) { echo "<option value=\"".$row['REGION']."\">".$row['REGION']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Region').value = <?php echo json_encode(trim($_POST['Region']));?>; </script> </select> On my next project that I'm working on now, I need to do the same thing, so I copied the above code amended, and placed in my new project: <select name="Sales_Exec" id="Sales_Exec"> <option value="">-- Select SE --</option> <?php $salesexec=$POST['Sales_Exec']; if ($salesexec); { $salesexecquery = "SELECT DISTINCT Assigned FROM Data "; $salesexecresult = mysql_query($salesexecquery); while($row = mysql_fetch_array($salesexecresult)) { echo "<option value=\"".$row['ASSIGNED']."\">".$row['ASSIGNED']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Sales_Exec').value = <?php echo json_encode(trim($_POST['Sales_Exec']));?>; </script> </select> This second chunk of code doesn't work... and I can't work out why as it seems I've copied it all and amended all the neccersary parts, can anyone spot what is wrong? Thankyou!

  • jQuery $().find problem

    - by Titanous
    I'm trying to get the contents of a XML document element, but the element has a colon in it's name. This line works for every element but the ones with a colon in the name: $(this).find("geo:lat").text(); I assume that the colon needs escaping. How do I fix this?

  • Function of: if(/(file|http).*/.test(url)) { }

    - by WmasterJ
    I am wondering what this technique is called and what it does. It seems to be validating some regular expression on the variable url. I am customizing another persons code: var url = document.getElementById("editorURL").value; if(/(file|http).*/.test(url)) { } Maybe someone has a link to an article that explains this a bit more in-depth?

    - by Blake
    I am looking to hover over my list item and have an effect similar to something like facebook chat is my best example..I am able to get the first div to appear but I believe this may be a selector issue because I cant get the rest working properly html <ul id="menu_seo" class="menu"> <li id="menu-seo"><span class="arrowout1"></span>SEO</li> <li id="menu-siteaudits"><span class="arrowout2"></span>Site Audits </li> <li id="menu-linkbuilding"><span class="arrowout3"></span>Link-Building</li> <li id="menu-localseo"><span class="arrowout4"></span>Local SEO</li> </ul> <div id="main_content"> <div id="menu-seo-desc"> <p>SEO management begins with a full website diagnosis of current web strategy Adjustments are made to improve your site’s ability to rank higher on search engines and draw more traffic </p> </div> <div id="menu-seo-desc2"> <p>Usability & site architecture review, Search Engine accessibility and indexing, Keyword research & targeting and Conversion rate optimization </p> </div> </div> css #menu-seo-desc { height:125px; width:210px; background-color:red; border-color:#CCC #E8E8E8 #E8E8E8 #CCC; border-style:solid; border-width:1.5px; border-radius:5px; box-shadow: 1px 0 2px 0px #888; -moz-box-shadow: 1px 0 2px 0px #888; -webkit-box-shadow: 1px 0 2px 1px #888; position:absolute; top:220px; left:350px; display:none; } js <script> $(document).ready(function(){ <script> $(document).ready(function(){ $('#menu_seo').on('#menu-seo', { 'mouseenter': function() { $('#menu-seo-desc').fadeIn(600); $('#menu-seo-desc2').fadeIn(600); }, 'mouseleave': function() { $('#menu-seo-desc').fadeOut(300); $('#menu-seo-desc2').fadeOut(300); } }); }); </script> });

  • Divs not aligning side by side

    - by Abijah
    I've been learning about divs over the past few months, and am now able to align divs side by side. However, today I was working on my website, and my divs suddenly stopped lining up. The divs in question are: #dorsey_left, #dorsey_middle and #dorsey_right. When I remove #dorsey_left from the HTML document, #dorsey_middle and #dorsey_right align properly. I'm guessing that the problem is related to #dorsey_left, but I can't find anything in the code. This is the JsFiddle.

  • JavaScript: Can I declare a variable by querying which function is called? (Newbie)

    - by belle3WA
    I'm working with an existing JavaScript-powered cart module that I am trying to modify. I do not know JS and for various reasons need to work with what is already in place. The text that appears for my quantity box is defined within an existing function: function writeitems() { var i; for (i=0; i<items.length; i++) { var item=items[i]; var placeholder=document.getElementById("itembuttons" + i); var s="<p>"; // options, if any if (item.options) { s=s+"<select id='options"+i+"'>"; var j; for (j=0; j<item.options.length; j++) { s=s+"<option value='"+item.options[j].name+"'>"+item.options[j].name+"</option>"; } s=s+"</select>&nbsp;&nbsp;&nbsp;"; } // add to cart s=s+method+"Quantity: <input id='quantity"+i+"' value='1' size='3'/> "; s=s+"<input type='submit' value='Add to Cart' onclick='addtocart("+i+"); return false;'/></p>"; } placeholder.innerHTML=s; } refreshcart(false); } I have two different types of quantity input boxes; one (donations) needs to be prefaced with a dollar sign, and one (items) should be blank. I've taken the existing additem function, copied it, and renamed it so that there are two identical functions, one for items and one for donations. The additem function is below: function additem(name,cost,quantityincrement) { if (!quantityincrement) quantityincrement=1; var index=items.length; items[index]=new Object; items[index].name=name; items[index].cost=cost; items[index].quantityincrement=quantityincrement; document.write("<span id='itembuttons" + index + "'></span>"); return index; } Is there a way to declare a global variable based on which function (additem or adddonation) is called so that I can add that into the writeitems function so display or hide the dollar sign as needed? Or is there a better solution? I can't use HTML in the body of the cart page because of the way it is currently coded, so I'm depending on the JS to take care of it. Any help for a newbie is welcome. Thanks!

  • jQuery: have a child window be notified when parent window goes to a different page?

    - by Heinrich Schmetterling
    i have a parent window and a child window. in javascript, i want a function in child window to be called whenever the parent window loads a new page. i'd like to use something similar to jQuery's $(document).ready() so that I don't have to worry about whether the parent is done loading yet - but ready() only appears to fire when the window loads the first page - but not when, say, a link is clicked in the parent and it loads a second page. any suggestions? thanks.
