Javascript how do rearrange or sort text inside text box

How do rearrange or sort text inside a text box

e.g "test test2"

I want to make "test2" at the front of the text box the page is submited or unloaded or whatever

Im n00b

 

or a button

 

Do you mean something like this:

<textarea id="box" cols="40" rows="5">
test test2
</textarea>
<br>
<input type="button" value="Swap Around!" onclick="document.getElementById('box').value='test2 test'">

Code (markup):

When you click the button, it finds the element's id and changes the value to whatever you want it to be. [/B]

 

Do you know any javascript?
1. Use the split function to split the value of the textbox using a space(" ") as the splitter, and store in an array.
2. You can then sort the array accordingly, it depends on how you want it sorted. Alphabetically is easy (just use the sort() method.
3. Clear the textbox and write the array back into it, using the join method to do this.

 

something like:

document.getElementById("submitButton").onclick = function() {
    var myTextbox = document.getElementById("myTextbox");
    var myArray;
    myArray = myTextbox.value.split(" ");
    myArray.sort();
    myTextbox.value = myArray.join(" ");
    return true;
}

Code (markup):

Where 'submitButton' is the ID of the button. And myTextbox is the ID of the textbox(or textarea).
