Question

Basically I want to make a function that, when the text is clicked, it prints the ‘id’ on the form. and when it’s clicked again, only that ‘id’ is deleted (prior clicked/printed ‘id’s remain).

The print script I have so far:

function imprime01(obj) {
        document.form2.text.value = document.form2.text.value +  obj.title;
         }

the div

<div onclick="imprime01(this);" title="240 ">240</div>
<div onclick="imprime01(this);" title="230 ">230</div>
<div onclick="imprime01(this);" title="220 ">220</div>

So what I want is: when I click 240, 230 it prints “240 230” on the form, and when I click “240” again, it deletes only “240” from the form. Is there a way to achieve this?

See http://jsfiddle.net/BdEMx/

function imprime01(obj) {
    var arr=document.form2.text.value?document.form2.text.value.split(' '):[];
    var i=arr.indexOf(obj.title);
    if(i===-1){
        arr.push(obj.title);
    }else{
        arr.splice(i,1);
    }
    document.form2.text.value = arr.join(' ');
}

You shouldn’t add a space at the end of title attributes only because you want to join some of them.
