Question

Displaying an image within a textarea using JS and CSS

Could someone help me create a form with textareas that have small images on them? I want clicking on the image to call a function fx(). Can anyone code this for me using JavaScript/jQuery/CSS?

In the image below, clicking on "GO" will call Fx()

I attempted it myself but failed (and don't know how to attach a function to the image)

.searchform {
display: inline-block;
padding: 3px 5px;
}
.searchform input {
font: normal 12px/100% Arial, Helvetica, sans-serif;
}
.searchform .searchfield {
background: #fff;
padding: 6px 6px 6px 8px;
width: 202px;
border: solid 1px #bcbbbb;
outline: none;
}
.searchform .searchbutton {
color: #fff;
border: solid 1px #494949;
font-size: 11px;
height: 27px;
width: 27px;
}


<form class="searchform">
<input id="t" class="searchfield" value="Search..." type="text">
<input class="searchbutton" value="Go" type="button">
</form>

Here is a solution for positioning an element over a textarea:

Start by placing the "go" element before the textarea and use position: absolute to position it in the top left corner of the area.
Then wrap both elements in a parent wrapper with position: relative.
Adjust the position of the "go" element using jQuery's .width() and .height() functions.

Here is the HTML structure:

<div id="wrapper">
<div id="go">Go</div> 
<textarea id="area" rows=33 cols=22></textarea>
</div>

The corresponding CSS:

#wrapper { position: relative }
#go { width: 16px; tpp: 16px; position: absolute; background-color: yellow }

And the JavaScript code to adjust the position of the "go" element:

$(function(){
$("#go").css("left", $("#area").width() - $("#go").width());
$("#go").css("top", $("#area").height() - $("#go").height());
});

You can view the implementation here: http://jsfiddle.net/WUnQW/

Alternatively, there is a simpler method that uses display: inline-block, but keep in mind that this may not work properly in older versions of Internet Explorer. You can see this alternative approach here: http://jsfiddle.net/WUnQW/6/

It is not possible to insert an image tag directly into a textarea unless it is used as a background image. A workaround for this limitation is to use a div with the contentEditable attribute, which mimics a textarea and allows for the insertion of an <img> tag. This is commonly how WYSIWYG editors function. Additionally, using simple CSS, you can position the image at the bottom right corner.

<div contentEditable="true"> type here
 <img id="textimg" src="..." />
</div>

To execute the function fx() when the image is clicked on, you can do the following:

function fx() {
    alert('this is a function');
}
$('#textimg').click(fx);

To integrate an image within a clickable anchor, enclose the image with an anchor tag

<div><a ... ><Image /></a>.</div>

and add the click attribute. Manipulate the positioning of the <div> using CSS for absolute placement.
