Jquery load with script tags
I read something about the .load function in jQuery. Is there a way to insert t开发者_JAVA技巧he script tags in the loaded page?
When I try to load a page the scripts doesn't load :s, I want to fix this. And getscript() isn't a option.
When .load() returns HTML content that contains <script> tags, jQuery strips out the <script> tags, moves them,1 executes them, and then removes them.
While this makes it hard to step through those scripts with a debugger, the scripts do execute.

1Either to the <head>, or the parentmost element — I haven't found an authoritative source on this yet, though I could just check the jQuery source...
Instead of using $(el).load I did a $.get, parsed the result en ev(i)lled ;) the scripts
For readibility and understanding I've tried to use variablenames that reflect their purpose and simplified it a lot. Ofcourse there should be some error handling here, but it's just a POC. HTH someone :)
Below *le code
var ajax_url = "mypage.htm";
var result_selector_filter = "#mynewcontent";
var element_to_update = $("#mycontent");
// below the statement that you'ld normally use
// element_to_update.load(ajax_url + ' ' + result_selector_filter);
$.get(ajax_url, function(response){
// parse the entire response into a jQuery object
var initial_parsed_result = $(response);
// find the selector that needed to be filtered
var result_node = initial_parsed_result.find(result_selector_filter);
// update the html
element_to_update.html(result_node.html());
// variables used while looping
var current_node,i;
// Loop the parsed result jQuery object, check if it's a script tag and evaluate it
for(i=0;i<initial_parsed_result.length;i++){
// create a jquery object for current looped result html
current_node = $(initial_parsed_result.get(i));
// check if current node is a script tag
// method always returns the tagname in CAPITALS
if(current_node.prop("tagName")=="SCRIPT") {
eval(current_node.html());
}
}
});
