JavaScript - Invoking A Function
Hi i cannot understand how to invoke this function animateCSS. I've firebug and it says that the arguments aren't being passed to the function as far as i can tell. it's just an example i'm try to get working from the rhino javascript book.
There aren't any actual JS errors in firebug i just don't know how to pass the information to the function. also how do you pass JS in a button? e.g. <button onclick="animateCSS(document.getElementById("h1"),40,50, {top: function(f,t){return 300-f*5 + "px"}, clip: function(f,t){return "rect(auto "+f*10+"px auto auto)";} });')">move</button> would that work? This is hard! Code: [script]
function animateCSS(element, numFrames, timePerFrame, animation, whenDone){
var frame= 0;
var time = 0;
//call the diplaynextframe section every 50 ms
var intervalId = setInterval(displayNextFrame, timePerFrame);
function displayNextFrame(){
if (frame >= numFrames){//when numframe gets to 0
clearInterval(intervalId); //stop calling this function
if (whenDone) whenDone(element);
return;
}
for(var cssprop in animation){
try{
element.style[cssprop] = animation[cssprop](frame, time);
}catch (e){}
}
frame++;
time += timePerFrame;
}
}
animateCSS(document.getElementById("h1"),40,50,
{top: function(f,t){return 300-f*5 + "px"},
clip: function(f,t){return "rect(auto "+f*10+"px auto auto)";}
});
[script]
<body onload="animateCSS()">
<h1>THIS IS A TEST</h1>

Similar TutorialsHi All, Need help with this issue..currently we are having a scenario wherein in a JSP page we invoke the Microsoft Outlook client (open the Outlook client) using ActiveX api.. This we are doing using a java Script function which is called when the JSP page gets loaded. The body of the email is pre populated in a HTML format when the Outlook client opens up. Now we have a requirement wherein we need to open up the Lotus Notes client in a similar way ..Could someone please advise/help how this could be achieved ..whether there are some standard api's which could be used here. 2. Also in case there are 10 users who are using microsoft outlook as their email client while the other 10 users are using lotus notes for emailing..then in this case how could this be handled.. waiting for some help regards these questions thanks 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. <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> 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 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> 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 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? I made a mouseover event of a caption on a picture, when I hover the opacity of the background color of the hover and the text goes down. What I want is that when I hover over the image which the caption is floating on, the onmouseover event gets activite. For an imaginary example: Code: function unhighlight(x) {
x.style.backgroundColor="transparent"
}
Function ActivationFuction()
{
activate.function="unhighlight"
}
thanks 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?

This is a very basic version of what I am trying to do. I have a dynamic list which is set in a table. When clicked, a function is run to set up a new list.. The reason I explain that, is that I need to keep it dynamic. Now for the problem: When I run this page, I have the button made right away, then when clicked it creates the new button. The new button should also run the function to create the new button again, but when I click it, I only receive "error on page". I don't know if there is a better way to go about this, but as for this route, I am stuck. Any help is greatly appreciated! -Shane Hi, Any one help me In one variable i have some data ex: var data = document.getElementById("imageId").value; I want to pass this data to another function inside another function ex: var button1 = '<img src="images/Remove-button.gif" width="70" height="15" onclick="removeVerifyImageRow(this),saveLibData('+data+')"/>'; while running the application i am getting an error incase if the data is string ex:if data is 'image1' i am getting an error, but with number there is no problem ex: if data is '1122'. this is very urgent to solve this problem plz any one help me 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. i have an image with an onclick function and parameters 0,1 i want to change the parameters of the onclick function through the same function? Code: <img id="down0" onclick=swap(0,1) />
<javascript>
function swap(a,b){
var imgda=document.getElementById('down'+a);
imgda.onclick = swap(b,b+1);
}
</javascript>
normally it should change the onclick to swap(1,2) but it remains 0,1 whats happening?? p.s. plz dont tell me about the javascript tag, its just for quick explaining... Hello again! Is there any way to pass a function(with its parameters) to another function using a parameter? Examples: Here is how I do it now: PHP Code: function output(text){ alert(text); } function bla(text, func){ output(text); } bla("Text is here", output) //Outputs "Text is here" I only want to pass the function to bla() as a parameter. I need something like this: PHP Code: function output(text){ alert(text); } function bla(func){ output(); } bla(output("Text is here")) //Outputs "Text is here" Is this possible in some way? Thanks in advance. (PS: I had no idea what to call this thread so, hopefully it's okay) I'm trying to make a time script for an app I'm making (this is not an HTML document; it's a .js file to be used with Titanium) however I'm having trouble getting the function to display and update. Code: function updateClock()
{
setInterval ( 'kiTime()', 1000 );
}
function kiTime ()
{
//Get current date and time
var currentTime = new Date ();
//Create variables for hours, minutes, and seconds from current time
var currentHours = currentTime.getHours ();
var currentMinutes = currentTime.getMinutes ();
var currentSeconds = currentTime.getSeconds ();
//Add a leading zero to minutes and seconds if less than ten
currentMinutes = ( currentMinutes < 10 ? "0" : "" ) + currentMinutes;
currentSeconds = ( currentSeconds < 10 ? "0" : "" ) + currentSeconds;
//Create the string of time data
currentTimeString = currentHours + ":" + currentMinutes + ":" + currentSeconds;
return currentTimeString;
}
var win3 = Titanium.UI.createWindow({
title:'Clock',
backgroundColor:'#fff'
});
var tab3 = Titanium.UI.createTab({
icon:'clock.png',
title:'Clock',
window:win3
});
var label3 = Titanium.UI.createLabel({
color:'#999',
text:updateClock(),
font:{fontSize:20,fontFamily:'Helvetica Neue'},
textAlign:'center',
width:'auto'
});
win3.add(label3);
If I use kiTime() under the text field I will get the current time (or at least the time the app was opened), however if I call updateClock() it's blank. Hi, I am working on a google map where you can show lines on the map by checking checkboxes. Lines are displayed according to their category attribute in the xml file. The function that picks up the checkbox click is like this: Code: function boxclick(box,category) {
if (box.checked) {
show(category);
} else {
hide(category);
}
Another part of the code assigns that category attribute to arrows, so that when a line of "x" category is displayed, the relevant arrows are displayed along with it, to indicate directionality. I also have a select list which displays the lines by looping through their array and using selectedIndex in a function called handleSelected2. But I can't get the arrows to display along with the lines from the select box. After trying many, many things, I figure that all I need to do is to call the show(category) function from inside the handleSelected2 function and it should all come together. So I came up with this: Code: function handleSelected2(opt,category) {
for (var h = 0; h <gpolylines.length; h++) {
gpolylines[h].hide();
}
h = opt.selectedIndex - 1;
if (h > -1) {
gpolylines[h].show();
}
for (var v=0; v<pts.length; v++) {
show(category);
}
}
which gets me lines, but no arrows. You can see it sort of working he http://www.xelawho.com/map/zonesarrowstest.htm I figure I've got to be close, because if I just tell it to show all the arrows (without going through the category filter) like this: Code: function handleSelected2(opt,category) {
for (var h = 0; h <gpolylines.length; h++) {
gpolylines[h].hide();
}
var h = opt.selectedIndex - 1;
if (h > -1) {
gpolylines[h].show();
}
for (var i=0; i<pts.length; i++) {
pts[i].show();
}
}
then all the arrows show up, as you can see he http://www.xelawho.com/map/zonesarrowstest2.htm I'm not getting any error messages and I've tried pretty much everything I can think of... I've been tweaking this for days and it's driving me crazy. Does anybody else have any ideas? Thanks in advance. Hello all. I have fairly simple questions regarding modifying this script: http://papermashup.com/create-a-dynamic-form-preview/ to dynamically show different parts of a form on another part of the page. I am looking to use it on most parts of my form and would like a little clarification. First is the use of $(document).ready(function() or $(function(). It works using either, my question is which is preferred? As I understand it using $(document).ready(function() starts the DOM immediately on page load and is useful if you need something right away. I am also using this script: http://www.dynamicdrive.com/dynamici...formwizard.htm for the form. Since the preview script is being used with the form to wizard, I don't really need it until the rest of the form loads. Another question would be, is there a cleaner way to go about using the preview script on say 10 different form inputs independently? For example in a single function rather than 10 different function/updates? I have an example of what I am trying he http://jsfiddle.net/anhyG/1/ Thank you in advance for any help! |
