Question

I have to write in a textarea but i have two “id” equal because i create the form for changing data.
If the form is:

<form method="GET" name="formparam" id="formparam" action="${nextstep}">
    <label>ID</label></td><td>
    <textarea class="expand" name="inputp'+v+'_id" id="inputp'+v+'_id">
    </textarea>
</form>

And for Call i use this script:

function qs(key) {
    key = key.replace(/[*+?^$.\[\]{}()|\\\/]/g, "\\$&"); // escape RegEx control chars
    var match = location.search.match(new RegExp("[?&]" + key + "=([^&]+)(&|$)"));
    return match && decodeURIComponent(match[1].replace(/\+/g, " "));
}

function Pcompila(v){
var i;
var Listparam=['_id','_description','_info','_type','_value'];
for (i=0;i<Listparam.length;i++)
{
var a ='inputp'+v+ Listparam[i];
alert(a);
    if (location.search) {
    var p=qs(a);
    alert(p);
            $('#'+a).text(p);

    }
}

        return;
    }

Where $('#'+a).text(p); is wrong because don’t write.
How to change for calling the id in a form???.
I try with this:

$("formparam").$('#'+a).text(p);

This is a absolute wrong!!!

Answer 1

$("formparam") is not correct because formparam is not an element type, it should be #formparam to search for an ID. And the way to search for one element inside another is to use .find(), e.g. $("#formparam").find("#"+a). But since IDs must be unique, you don’t really need to say where to search for them, so you can just use $("#"+a), as in Pulkit Mittal’s answer.
