This is what I am currently doing to trim all of my value. It is ugly and a too repetitive.

var strHTML = '';
$.getJSON('info.php',
    function(data) {
        $.each(data, function(i, item) {
            strHTML += $.trim(item.fname) +
                       $.trim(item.lname) +
                       $.trim(item.address) +
                       $.trim(item.phone) +
                       ...(about 10 more of these);
        });
    });

There ought to be a better way to do this.

• php
• javascript
• jquery
• json
• trim

• Is there no $(item).each(function(j){ strHTML+= $.trim(this[j])} ??? – mplungjan Commented Mar 24, 2011 at 17:42
• mplungjan doesn't work. I need the flexibly to concatenate my html along with this, but I left it out b/c of the mess. – nolabel Commented Mar 24, 2011 at 22:21

A for...in example, with hasOwnProperty:

var obj = {
    foo: ' bar',
    blahblah: ' ahahaha   '
};

var arr = [];
for (key in obj) {
    if (obj.hasOwnProperty(key)) {
        arr.push($.trim(obj[key]));
    }
}
alert(arr.join(','));

I'd say you should trim the data on the PHP-side, as it's your PHP script that generates it ¹.

Basically : make sure your info.php script generates correct data.

And if your data is stored in an array, you can apply that function to all items of that array using the array_map() function :

$data = array_map('trim', $data);

If you want all properties of item to be trimmed you can use the for (props in item) {} -loop to loop through all of them. Because u can use this on all javascript-object you can create a function that does the trimming on all properties of an object.
