JavaScript - Need Help In Making The Function Thats Tied To A...
I was wondering if someone could help me make this function that's tied to a HTML select work on an <imput type="image">.
Ideally what I would like to do is tie everything to the <input type="image"> , right now the way the code works is that when I choose yes or no the image on the <img src=""> changes. So basically when I choose yes or no in the select what I would like the image source to change for the <input type="image"> assuming it's possible. Ty... See my demo page for where I have it working on an img src but not an input which is what I really want. Here's the link again to my testing / demo page: http://www.myu2sig.com/stellardonations/buttontype.php Now for all of the code that produces what you see on said page. Code: <script type="text/javascript">
function showimage(t){
if (!document.images)
return;
document.images[t.getAttribute("name").replace("select","pics")].src=t.options[t.selectedIndex].id
}
</script>
Regular Image using: < img name="firstpics" src="/stellardonations/paypaldonate.gif"><br />
<img name="firstpics" src="/stellardonations/paypaldonate.gif">
<br /><br />
Input Image using: < input type="image" src="/stellardonations/paypaldonate.gif" border="0" name="submit" ><br />
<input type="image" src="/stellardonations/paypaldonate.gif" border="0" name="submit">
<br /><br />
<select name="firstselect" onChange="showimage(this)">
<option id="/stellardonations/paypalsubscribe.gif" value="Yes">Yes</option>
<option selected="selected" id="/stellardonations/paypaldonate.gif" value="No">No</option>
</select>

Similar TutorialsHi, I have this code: Code: window.addEvent('domready',function(){
document.id('cool').addEvent('click',function() {
light = new LightFace.IFrame({ height:400, width:800, url: 'http://google.com', title: 'Google!' }).addButton('Close', function() { light.close(); },true).open();
});
});
It's a piece from something called the lightface iframe. What I want to do is to have this code on my javascript page, that's included on the main page where I want to call it. I call on it like this: Code: <a href="#" id="cool">Edit general info</a> However this only works if it's on the main page, not when I have it on my js page. So what I want to do is to turn it into a function, because that I know works. Could anyone help me with this? Thanks in advance for your time!

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. 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 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> 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? 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 Code: <html>

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 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. 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> 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 Okay so to be short, I'm trying to make a script similar to a link checker but instead of having to input each link in one by one and click a button (A button saying Validate, for instance), I was looking for something that would do it automatically? Example - 1. First I input the link http://www.example.com/posts.php?do=1000000000 and click Start or Validate. 2. After clicking Start or Validate, the validator or script would begin checking links, modifying the http://www.example.com/posts.php?do=1000000000 to http://www.example.com/posts.php?do=1000000001 and so on and so on, until it reached all 9's. 3. After the scanning, every existent link (Meaning links that didn't give the 404, or re-direct to another page) would be displayed in the page below or a log file. I really appreciate the help everyone, since I'm still into learning about Javascript. Thanks in advance! Hello, I'm un-sure on what I should have called this topic so sorry for the possibly mis-leading topic name. Firstly, my menu bar is attached to the top of the clients screen as seen here. Secondly, I've been wondering how could I make it so when a button is pressed another div around 40px in height would appear above it(that div is also attached to the clients screen). For example I saw http://9gag.com/, when you click on search button in the top right hand corner the search bar appears ontop of the menu bar. My JavaScript knowledge is very limited, I know how to make a div appear with the click of a button, but how can I make it be attached to the top of the clients browser and the menu bar in under it?

Thanks for reading and hopefully somebody can point me in the right direction. I'm working on making a searchable javascript and DOM reference...A chm like what php has. I mainly need it for myself because I don't always have access to the net. I was wondering if anyone would like to contribute? I'm decent at JavaScript but I have no idea how I should go about making a calculator. So far I'll drop a bunch of buttons down that all onclick to a function (a,b) and then it will add or w/e then return. How would I incorporate multiple methods such as subtraction or multiplication though? Basically I'm confident I the ability to code or learn to make this calculator, just have no idea how to set this up, thanks. |
