jQuery, run only if element exists

.on('load',...) or .length

[csdude55]

I only want a function to run if an element exists on the page... which would you guys do, and why?

if ($(element).length) {
 // do this
}

$(element)
 .on('load', function() {
  // do this
 });

Use pure JavaScript so you don't put an artificial death-clock on your code. Feel free to browse the JavaScript functions in the documentation of my website in my profile.

if (id_('example')) {alert('the element exists!');}

function id_(id)
{
 if (id == '' && window['console']) {console.log('Developer: empty id called from: '+id_.caller.toString().split('function ')[1].split('(')[0]);}
 return (document.getElementById(id)) ? document.getElementById(id) : false;
}

if ($(element).length > 0) {
// do this
$(element)
.on('load', function() {
// do this
});
}
