I'm using the jQueryify bookmarklet on a page so that I can call jQuery functions from the console. But everytime I invoke a jQuery function on a selected object, I get the error:
"TypeError: jQuery("li")[0].children[0].html is not a function
[Break On This Error] jQuery('li')[0].children[0].html();
I have tried this in FireBug as well as Google Chrome's Webkit console.
You are no longer working with jQuery objects when using square braces.
jQuery("li")[0]
This returns you the 1st li
as a DOMElement, not a jQuery object.
jQuery("li")[0].children[0]
This returns the 1st li
's 1st child as a DOMElement, not a jQuery object.
.html()
This function only works for jQuery objects. For DOMElements, you can use the .innerHTML
property.
I suggest instead of dealing with DOMElements, you should continue working with jQuery objects. Try using this instead:
jQuery('li').eq(0).children().eq(0).html()
It looks like you are trying to call a jQuery function, html
, on a DOM object children[0]
. Try wrapping that in a jQuery object and then calling html
var temp = jQuery("li")[0].children[0];
var html = jQuery(temp).html();
Check the result of jQuery("li")[0].children[0]
, it's a regular DOM object NOT a jQuery object. Without seeing your HTML i can't recommend a better selector but a cheap and dirty fix would be
jQuery(jQuery('li')[0].children[0]).html();
This will convert the DOM object result into a jQuery object which has the .html()
function.
Try following
jQuery(jQuery("li")[0].children[0]).html();
or better one
jQuery("li:eq(0)").children(':eq(0)').html();
or another one
jQuery("li:eq(0)").children().eq(0).html();
even this one will work
jQuery("li").eq(0).children().eq(0).html();
Accessing the array elements on the jquery object (using []) returns a DOMElement, which obviously doesn't have jquery's methods. You probably want to use eq()
instead.
