Question

I give you what I want in PHP :

foreach($myarray as $key=>$value) { ${$key} = $value; }

Now, can we do it with JS/jQuery ?

This is the jQuery input, I want the classTD value as key, in other words the equivalent of the famous PHP statement ${$key} in the example above:

data  = {};
$('#resul_rech_doc_fact tr.document-2 td').each(function(index) {
var classTD = $(this).attr('class');
var contentTD = $(this).text();
data = $.extend(data , { classTD : contentTD });
});

Answer 1

The line:

data = $.extend(data , { classTD : contentTD });

Doesn’t do what you expect. It is identical to:

data = $.extend(data , { 'classTD' : contentTD });

It seems you want to evaluate classTD and sue it as the object’s key. You have two options:

You can assign the data member, modifying data:

data[classTD] = contentTD;

or you can use $.extend with a temporary object:

var obj = { };
obj[classTD] = contentTD;
data = $.extend(data, obj);
