  • JavaScript: count minimal length of characters in text, ignoring special codes inside

    - by ilnur777
    I want to ignore counting the length of characters in the text if there are special codes inside in textarea. I mean not to count the special codes characters in the text. I use special codes to define inputing smileys in the text. I want to count only the length of the text ignoring special code. Here is my approximate code I tried to write, but can't let it work: // smileys // ======= function smileys(){ var smile = new Array(); smile[0] = "[:rolleyes:]"; smile[1] = "[:D]"; smile[2] = "[:blink:]"; smile[3] = "[:unsure:]"; smile[4] = "[8)]"; smile[5] = "[:-x]"; return(smile); } // symbols length limitation // ========================= function minSymbols(field){ var get_smile = smileys(); var text = field.value; for(var i=0; i<get_smile.length; i++){ for(var j=0; j<(text.length); j++){ if(get_smile[i]==text[j]){ text = field.value.replace(get_smile[i],""); } } } if(text.length < 50){ document.getElementById("saveB").disabled=true; } else { document.getElementById("saveB").disabled=false; } } How the script should be in order to let it work? Thank you!

  • JavaScript Resource Management Design Pattern

    - by Adam
    As a web developer, a common problem I find myself tackling is waiting for something to load before doing something else. In particular, I often hide (using either display: none; or visibility: hidden; depending on the situation) elements while waiting for a background image or a CSS file to load. Consider this example from Last.FM. They overlay a semi-transparant PNG over each album art image so that it looks like it's inside a jewel-case. They let it load when it loads, so depending on your internet speed, you may see the art image by itself (without the overlay) temporarily. In this case, the album art looks fine without the jewel-case effect. But in similar situations, I have found that I don't want the user to see the site's design mangled as resources incrementally load. So, in rare cases I have hidden everything from the user until the whole kit and kaboodle has loaded. But this is often a pain to write out, and may force the user to wait for a pretty long time to see anything (besides "loading..." text). I can think of (and have used on occasion) some obvious solutions/compromises: Use some inline CSS so that as certain parts of the DOM load and render, they will immediately have the correct size/position/etc. Immediately render the navigation part of the site, so that if the user wanted to use the current page purely to get somewhere else, they don't have to wait for the rest to load. Load pixelated images first as placeholders for layout while lazy-loading higher quality images as replacements. Something quirky like using a cute animated gif to distract the user during a "loading..." phase. Show useful information as a reference while loading the full UI. (Something akin to Gmail Inbox Preview, etc.) (Sorry if my question was basically just asked and answered...) Despite all of these ideas, I still find myself hoping there are better ways of doing some of these things. So I guess what I'm looking for is some inspiration and/or any creative ways of dealing with this problem that you guys may have seen out in the wild.

  • Use Javascript RegEx to extract column names from SQLite Create Table SQL

    - by NimbusSoftware
    I'm trying to extract column names from a SQLite result set from sqlite_master's sql column. I get hosed up in the regular expressions in the match() and split() functions. t1.executeSql('SELECT name, sql FROM sqlite_master WHERE type="table" and name!="__WebKitDatabaseInfoTable__";', [], function(t1, result) { for(i = 0;i < result.rows.length; i++){ var tbl = result.rows.item(i).name; var dbSchema = result.rows.item(i).sql; // errors out on next line var columns = dbSchema.match(/.*CREATE\s+TABLE\s+(\S+)\s+\((.*)\).*/)[2].split(/\s+[^,]+,?\s*/); } }, function(){console.log('err1');} ); I want to parse SQL statements like these... CREATE TABLE sqlite_sequence(name,seq); CREATE TABLE tblConfig (Key TEXT NOT NULL,Value TEXT NOT NULL); CREATE TABLE tblIcon (IconID INTEGER NOT NULL PRIMARY KEY,png TEXT NOT NULL,img32 TEXT NOT NULL,img64 TEXT NOT NULL,Version TEXT NOT NULL) into a strings like theses... name,seq Key,Value IconID,png,img32,img64,Version Any help with a RegEx would be greatly appreciated.

  • Why doesn't javascript function aliasing work?

    - by codeninja
    I have some Firebug console function calls that I wanted to disable when Firebug wasn't enabled, e.g. console isn't defined. This works fine in IE6 and FF3, but not in Chrome: var log; if(console){ log = console.log; }else{ log = function(){ return; } } I get an "Uncaught TypeError: Illegal Invocation" in Chrome =/ I read about the issue here, where you have to apply a context, which is kind of new to me... and I can't seem to figure how to accomplish the above in all browsers...

  • How to specify a font from javascript?

    - by Steven Lu
    I am trying to customize a view-src bookmarklet for iPad. This one is looking pretty good so far. But I want to make it just a little more readable: The Courier (New) font is a bit ugly even (especially?) on the retina display and I'd prefer any one of DejaVu Sans Mono, Monaco, Lucida Console, Bitstream Vera Sans Mono. I tried to modify the bookmarklet script by adding: pre.style.fontFamily = '"DejaVu Sans Mono", "Lucida Console", Monaco;'; It's not doing the trick. Perhaps prettyprint cancels out my fontFamily setting when it loads. Maybe I can set it at the end of the script somehow...

  • How to check for empty values on two fields then prompt user of error using javascript

    - by Matthew
    Hello guys, I hope I can explain this right I have two input fields that require a price to be entered into them in order for donation to go through and submit. The problem that I am having is that I would like the validation process check to see if one of the two fields has a value if so then proceed to submit. If both fields are empty then alert. This is what I have in place now: function validate_required(field,alerttxt) { with (field) { if (value==null||value=="") {alert(alerttxt);return false;} else {return true} } } function validate_form(thisform) { with (thisform) { if (validate_required(input1,"Need a donation amount to continue")==false) {input1.focus();return false;} else if (validate_required(input2,"Need a donation amount to continue")==false) {input2.focus();return false;} } } I would like to ultimately like to get this over to Jquery as well Thanks guys any help would do Matt

  • javascript replace div tags for p tags where it has no class

    - by Tom
    I would like to replace div tags for p tags but only when the div tag does not have a class. So this: <div class="myDiv"> <div>sdfglkhj sdfgkhl sdfkhgl sdf</div> <div>dsf osdfghjksdfg hsdfg</div> </div> Would become: <div class="myDiv"> <p>sdfglkhj sdfgkhl sdfkhgl sdf</p> <p>dsf osdfghjksdfg hsdfg</p> </div> I've tried .replace("<div>", "<p>").replace("</div>","</p>") but this replaces the closing tag of the one with a class.

  • Finding the closest grid coordinate to the mouse onclick with javascript/jQuery

    - by Acorn
    What I'm trying to do is make a grid of invisible coordinates on the page equally spaced. I then want a <div> to be placed at whatever grid coordinate is closest to the pointer when onclick is triggered. Here's the rough idea: I have the tracking of the mouse coordinates and the placing of the <div> worked out fine. What I'm stuck with is how to approach the problem of the grid of coordinates. First of all, should I have all my coordinates in an array which I then compare my onclick coordinate to? Or seeing as my grid coordinates follow a rule, could I do something like finding out which coordinate that is a multiple of whatever my spacing is is closest to the onclick coordinate? And then, where do I start with working out which grid point coordinate is closest? What's the best way of going about it? Thanks!

  • Javascript function variables being validated before function called by Internet Explorer

    When my page loads it calls the function like below: <body onLoad='changeTDNodes()'> And the code it calls is below: function applyThresholds(myvalue, mycell) { var threshold = 10; if (myvalue.innerHTML >= threshold) { //mycell.style.setAttribute('cssText','font-size:x-large;'); mycell.setAttribute('bgColor','red'); } else { mycell.setAttribute('bgColor','green'); } } function changeTDNodes() { // there can be many 'td' elements; just return the nth element var RepairVideo_cell_value = document.getElementsByTagName('B')[21]; var RepairVideo_cell = document.getElementsByTagName('td')[16]; var PPV_cell_value = document.getElementsByTagName('B')[6]; var PPV_cell = document.getElementsByTagName('td')[1]; var LeadRepair_cell_value = document.getElementsByTagName('B')[11]; var LeadRepair_cell = document.getElementsByTagName('td')[6]; var LeadTier_cell_value = document.getElementsByTagName('B')[16]; var LeadTier_cell = document.getElementsByTagName('td')[11]; var CHSI_cell_value = document.getElementsByTagName('B')[26]; var CHSI_cell = document.getElementsByTagName('td')[21]; var HN_cell_value = document.getElementsByTagName('B')[31]; var HN_cell = document.getElementsByTagName('td')[26]; var CDV_cell_value = document.getElementsByTagName('B')[36]; var CDV_cell = document.getElementsByTagName('td')[31]; var CommOps_cell_value = document.getElementsByTagName('B')[42]; var CommOps_cell = document.getElementsByTagName('td')[36]; applyThresholds(PPV_cell_value, PPV_cell); applyThresholds(LeadRepair_cell_value, LeadRepair_cell); applyThresholds(LeadTier_cell_value, LeadTier_cell); applyThresholds(RepairVideo_cell_value, RepairVideo_cell); applyThresholds(CHSI_cell_value, CHSI_cell); applyThresholds(HN_cell_value, HN_cell); applyThresholds(CDV_cell_value, CDV_cell); applyThresholds(CommOps_cell_value, CommOps_cell); } Although the code executes succssfully, in the bottom corner of internet explorer the error shows as: Line: 12 Char: 1 Error: 'innerHTML' is null or not an object Code: 0 Yet if I move the applyThresholds function below the changeTDNodes function, the changeTDNodes functions complains that there is no such thing as the applyThresholds function.

  • Indirect function call in JavaScript

    - by Art
    There are things like f.call(...) f.apply(...) But then there's this (1, alert)('Zomg what is this????!!!11') "1" does not seem to mean much in this context, the following works just fine: (null, alert)('Zomg what is this????!!!11') (1, null, alert)('Zomg what is this????!!!11') (undefined, alert)('Zomg what is this????!!!11') Could you point to a specific part of ECMAScript which describes that syntax?

  • Find Line Above or Below in Javascript

    - by Dark Falcon
    I am working on an in-place HTML editor, concentrating on Firefox only right now. I have an element inserted where the cursor should be and also have left and right arrows working, but I can't seem to find a way to find: Start and end of a line for the home and end keys The next line up or down for the up/down arrows. I see document.elementFromPoint, but this doesn't get me a Range object. The Range object itself seems rather useless when it comes to using pixel positions.

  • Javascript: addClassName if input is checked and removeClassName if it was un-checked

    - by BoDiE2003
    Im trying to select all the li tags of the document and check if it hasClassName('yes') so if it has, it will remove it. But im having a TypeError: Object [object HTMLLIElement], has no method 'hasClassName' error. This is the DOM method: document.observe("dom:loaded", function() { $(document.body).select('input').each(function(element) { element.observe('click', function() { init(); }); init(); }); }); The previous code will take the init fuction and check the if there are checked inputs and add them the 'yes' class name, but if I un-check those inputs, the class remains. This is the funcion that Im trying to do dynamic (add and remove class 'yes'); function init() { $(document.body).select('input').each(function(element) { if (element.checked) { element.up('li').addClassName('yes'); } if ($(document.body).select('li').hasClassName('yes')) { element.removeClassName('yes'); } }) } Can you help me solving the last part of this function, so the removeclassname method will work? Thank you
