JavaScript - A Function Decleration Question.
$.fn.superfish = function(op)
{ } So I see here that a function is being declared and the name of the function is '$.fn.superfish'. Is there any special meaning at all behind the $ in this situation? Similar TutorialsHello I have a question which has been bugging me for a while now so have decided to ask it on CF. In PHP you can use the '&' symbol as a function operator for example like so. PHP Code: function demoFunc(&$output='') { for($i=1;$i<count(func_get_args());$i++) { $output .= ' '.func_get_arg($i); } $output = trim($output); } As you can see the '&' symbol was used in the argument section to allow the function to be used like this demoFunc($output,'hello','world'); print $output; My question is how can I do this in JavaScript to do the same thing like use the variable used in the function argument section and use it like it would be used in PHP? Thank you - DJCMBear Here is my webpage (don't laugh!). If you click on Espanol it translates the page to Spanish. English is set up differently and it works too. Please tell me why clicking Spanish works but not French, Portuguese, etc. Code: <body>

I have a dice simulator. Basically, a user enters how many sides they want on their die, and then I digitally roll 2 of them. And produce the output in a document.writeln. I think I'm having trouble with the this.sides in the constructor function (in the head section). Also, I'm getting a syntax error in Safari : 25TypeError: 'null' is not an object (evaluating 'element.value') Am I not suppose to put the variable in the constructor function? Any help would be appreciated. <head> var element = document.getElementById("number"); var sides = element.value; function Die( ) { this.sides = sides; this.roll = function( ) { return parseInt((Math.random( ) * 1000) % this.sides) + 1; } } </script> </head> <body> <h1>Adam's Dice Rolling Game!</h1><br/> <form action="" method="post"> <p> <input type="text" name="number" id="number"/> </p> <p> <input type="button" value="Roll the dice!" id="roll_me"/> </p> </form> <script type="text/javascript"> var d = new Die( ); d.sides = sides; var rolled_value = d.roll( ); var r1 = document.getElementById( "roll_me" ); r1.onclick = function Die () { document.writeln ( d.roll () ); } </script> I've been going through this great tutorial on how to implement a type-ahead feature on a text field and there's something which hopefully you guys can explain. On the third page there is this function. Code: AutoSuggestControl.prototype.init = function () {
var oThis = this;
this.textbox.onkeyup = function (oEvent) {
if (!oEvent) {
oEvent = window.event;
}
oThis.handleKeyUp(oEvent);
};
};
What I don't understand is this line: this.textbox.onkeyup = function (oEvent) { I know about anonymous functions, but I don't know where the value for the parameter oEvent is going to come from. Can someone explain this? Thanks! :) Hi! This is probably a classic inheritance thing... I have two objects, C1 and C2. Both contains a callback method named 'callback'. Now, if I let C2 inherit from C1, then C1's 'callback' gets overridden by C2's. The problem is I still want C1's methods to access their own 'callback' method. Is this possible, and is it "valid"? Am I headed down disaster lane here? Should I re-think and refactor? Example: Code: function C1 () {};
C1.prototype.callback = function () {
console.log('c1 called');
};
C1.prototype.call = function () {
//do stuff
this.callback();
};
function C2 () {};
C2.prototype = new C1();
C2.prototype.callback = function () {
console.log('c2 called');
};
var obj = new C2();
obj.call();
Output: c2 called Regards Don Hi there I am wondering if anyone can tell me the best way to access the functions of an Iframe from the parent of the frame. I have tried Code: var myFrame = document.getElementById('gigmap');
myFrame.flashMouseover(gid);
and Code: window.frames['gigmap'].document.flashMouseover(gid); though these didn't work. Basically this is what i want: Mainpage function a(id) receives flash variable 'id' then sends variable 'number' to iframe function b(id) . The part in red is where I have the problem. In case you are wondering what I am doing is sending an id of a gig in my database when its button rolled over in a flash swf to a Google Map (using Google maps javascript API inside the Iframe 'gigmap) and make the corresponding marker on the map jump. I have it so the iframed map markers send to the flash file on rollover though not the other way round...yet! Is it possible to have an input that points to some other function? For example: Code: function someFunction() {
alert('It worked.');
}
function doAnotherFunction(doIt, otherFunction) {
if (doIt == true) {
otherFunction();
}
}
<input type="button" value="test" onClick="doAnotherFunction(true, someFunction());">
Or would I need a switch statement and have all the various functions hardcoded? which is the real difference between: <script> alert('hello'); </script> and <script> function hi() {alert('hello');} </script> thanks in advance makerjoe Hi, I'm having some issues turning this "Please Wait"/Disabled button into a function. Code: <input type="submit" value="Submit Form" onClick="this.disabled = 'true'; this.value='Please wait...';" /> Code: function pleasewait()
{
this.disabled = 'true';
this.value='Please wait..'
}
<input type="submit" value="Submit Form" onClick="pleasewait();" />
Thanks much Hi, I am facing a problem in passing replace() function as an argument in user defined java function, can any one help me how to resolve it? intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '\' to '\\' I am posting my javascript function he <a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\\/g,"\\\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a> function OpenDocPreview(url, docname) { alert('message from search base : ' + url + ' ' + docname); } thank you, I was working on a tutorial for some ajax uploading stuff and I ran across a new function syntax I don't recognize. I am not a Javascript pro, but I am not a newbie either. here is the code I am working on: Code: function handleFileSelect(e){
var files = e.target.files;
var output = [];
for(var i=0,f;f=files[i];i++){
if(f.type.match('image.*')){
var reader = new FileReader();
reader.onload = (function(theFile){
return function(e){
var span = document.createElement('span');
span.innerHTML = ['<img class="thumb" src="',e.target.result,'" title="',theFile.nbame,'" />'].join('');
document.getElementById('list').insertBefore(span,null);
};
})(f);
reader.readAsDataURL(f);
}
}
document.getElementById('list').innerHTML = '<ul>'+output.join('')+'</ul>';
}
document.getElementById('files').addEventListener('change',handleFileSelect,false);
To be a little more clear, the code in question is that is the very middle. The syntax I don't understand is: Code: class.event = (function(arguments){
//stuff you put in a function...
})(more Arguments?);
I tried to customize a simple one to learn for myself and I wrote this: Code: var a = 'A';
var b = 'B';
test = (function(t){
alert(t);
alert(b);
})(b);
test(a);
The browser would alert 'B' and that's it. The console would tell me that 'test is not a function.' OK, so I am confused. The topmost code works. What I am wondering is what the syntax is called for creating a function (or event listener?) that way, and how it works. Although if I new what it was called I could just google how it works. i keep getting error Call to undefined function codeandurl() below is my code PHP Code: <?php $value= strip_tags(get_field('link',$post)); $resultid=get_field('resultid',$post); codeandurl($resultid,$value); ?> <div id="result"></div> <script type="text/javascript"> function codeandurl(resultid,url){ $( "#result" ).text(resultid); $( "#result" ).dialog({ modal: true, buttons: { Ok: function() { $( this ).dialog( "close" ); } } }); window.open(url); return false; } </script> <p> <script type="text/javascript">// <![CDATA[ var metrics = { "mm" : 1, "cm" : 10, "m" : 1000, "inch" : 25.4, "foot" : 304.8 }; function convert(num, dec){ var val = document.getElementById("fromVal").value; if(isNaN(val)){ return } function roundNumber(num, dec) { var result = Math.round( Math.round( num * Math.pow( 10, dec + 1 ) ) / Math.pow( 10, 1 ) ) / Math.pow(10,dec); return result; } document.getElementById("toVal").value = val * metrics[document.getElementById("fromSystem").value]/ metrics[document.getElementById("toSystem").value]; } var interval = null; function watchChanges(){ interval == null ? setInterval("convert()", 500) : clearInterval(interval); } // ]]></script> </p> <table> <tbody> <tr> <td><input id="fromVal" style="width: 100px;" onfocus="watchChanges()" onblur="watchChanges()" type="text" /><select id="fromSystem" onchange="convert()"> <option value="mm">millimeters</option> <option selected="selected" value="cm">centimeters</option> <option value="m">meters</option> <option value="foot">feet</option> <option value="inch">inches</option> </select></td> </tr> <tr> <td colspan="1" align="center">=</td> </tr> <tr> <td><input id="toVal" style="width: 100px;" type="text" disabled="disabled" /><select id="toSystem" onchange="convert()"> <option value="mm">millimeters</option> <option value="cm">centimeters</option> <option value="m">meters</option> <option selected="selected" value="foot">feet</option> <option value="inch">inches</option> </select></td> Hi! I'm trying to toggle a class and one works and the other does not and I don't know why. I'm just getting my feet wet with jquery and javascript and I figured this was a pretty easy task to take on! Maybe. Link to the page: Franklin Township Soccer Club - Change Field Status My sad, sorry attempt =| Code: $( "li.open" ).click(function() {
$( this ).toggleClass( "closed" );
});
$( "li.closed" ).click(function() {
$( this ).toggleClass( "open" );
});
The first function works with open, so I figured I'd just use opposite on closed! Ha! I don't think so! In the end within those function there is an element in a form on that page it's hidden. I'd like to change the value from a 0 to 1 for vice versa. That' will be my next step. If you could give me a little nudge in the right direction I'd appreciate it! But first understanding why one works and the other does not, that is the primary mission! I do appreciate any help given! Dave I found this script, and it works great: Code: <script type="text/javascript">
function disable(element)
{
var input = document.getElementById(element).getElementsByTagName("input");
for(var i = 0; i < input.length; i++)
{
input[i].setAttribute("disabled","true");
}
}
</script>
I tried to make the inverse by simply reversing the setAttribute() like so: Code: <script type="text/javascript">
function enable(element)
{
var input = document.getElementById(element).getElementsByTagName("input");
for(var i = 0; i < input.length; i++)
{
input[i].setAttribute("disabled","false");
}
}
</script>
But that didn't do it. Can someone show me why, and how to fix it? Here's the sample form which I'm trying to test it on: Code: <form>
<input type="radio" name="test" onclick="disable('D1')" /> disable<br/>
<input type="radio" name="test" onclick="enable('D1')" /> enable<br/>
<fieldset id="D1">
<input class="" type="text" value="test value1" /><input class="" type="text" value="test value2" /><br/>
<input class="" type="text" value="test value3" /><input class="" type="text" value="test value4" /><br/>
<input class="" type="text" value="test value5" /><input class="" type="text" value="test value6" /><br/>
</fieldset>
</form>
Edit: The ultimate goal which I'm working toward now (step by step =) is to have a form more like: Code: <form>
<input type="radio" name="test" onclick="disable('D1')" />
<fieldset id="D1">
<input class="" type="text" value="test value1" /><input class="" type="text" value="test value2" />
</fieldset>
<input type="radio" name="test" onclick="disable('D2')" />
<fieldset id="D2">
<input class="" type="text" value="test value3" /><input class="" type="text" value="test value4" />
</fieldset>
<input type="radio" name="test" onclick="disable('D3')" />
<fieldset id="D3">
<input class="" type="text" value="test value5" /><input class="" type="text" value="test value6" />
</fieldset>
</form>
And have the fieldsets enable and disable according the selection of the radio buttons. Also, the fieldsets (and their ID's) will be dynamically generated via PHP Thanks-a-bunch, ~ Mo Hi All, I'm trying to convert an anonymous function to a real function (nesting is getting out of hand), however the msg object becomes undefined after conversion. Here is the converted anonymous function which fails: https://gist.github.com/2587613 and here is the original anonymous function which works: https://gist.github.com/2587667 Any help would be greatly appriciated I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE). The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden. However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case. Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed? How can I call a PHP Function inside a Javascript Function? This is what I have so far, but I don't think I'm doing it the right way. Any suggestions? PHP Code: <?php function phpQuery(){ $query = mysql_query("INSERT INTO mytable VALUES('','name','email')"); } ?> <script type="text/javascript"> function delayQueries() { timeoutID = window.setTimeout(doQueries, 2000); } function doQueries() { var runQuery = "<?php phpQuery(); ?>"; } </script> Thank you in advance if someone can help. I have been banging my head against the wall for hours now. Here is the code: Code: for (var i = 0; i < BS_crm['activityTypes'].length; i++) {
var clickFunc = function(){ activityList.showForm( -1, {blockType:[""+BS_crm['activityTypes'][i]['id'], "0"]} ); };
var type = {
value: BS_crm['activityTypes'][i]['id'],
label: "Add New "+BS_crm['activityTypes'][i]['label'],
css: BS_crm['activityTypes'][i]['css']+"_16",
onClick: clickFunc
};
previewLinks.items.push( type );
}
Now, basically what I am doing here is running through one array to create an array of objects, that will be used to create links that will use whatever onClick function I pass it. The problem is that on the second line I need the BS_crm['activityTypes'][i]['id'] to be a value, not a reference. If that line was simply changed to: Code: var clickFunc = function(){ activityList.showForm( -1, {blockType:["3", "0"]} ); };
then everything would work as I need. How can I make this happen? I would really appreciate any help. Thank you again in advance. |
