是否可以在同一页面上加载多个不同版本的jQuery? [英] Is it possible to load multiple different version of jQuery on the same page?
问题描述
我正在制作一个bookmarklet,如果找不到该对象,它将加载jQuery.加载将检查jQuery的版本.代码如下:
I'm making a bookmarklet which will load jQuery if the object is not found. The loading will check on the version of jQuery. The code is like:
(function(){
var myBkl = {
loadScript: function(src) {
if(window.jQuery && window.jQuery.fn.jquery == '1.3.2'){
return;
}
var s = document.createElement('script');
s.setAttribute('src', src);
s.setAttribute('type', 'text/javascript');
document.getElementsByTagName('head')[0].appendChild(s);
},
whenLoaded: function(callback){
if (typeof(window.jQuery) !== 'undefined' && window.jQuery.fn.jquery == '1.3.2') {
callback(window.jQuery);
}
else {
setTimeout((function() {myBkl.whenLoaded(callback); }), 100);
}
},
init: function($){
console.log($.fn.jquery);
}
};
myBkl.loadScript('http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js');
myBkl.whenLoaded(myBkl.init);
})();
我使用此书签创建器来创建书签 http://subsimple.com/bookmarklets/jsbuilder.htm

很明显,如果页面已经加载了jQuery. 1.3.2脚本的加载将覆盖页面上的window.jQuery对象.我只是想知道是否有让1.3.2加载到另一个自命名变量的方法?使用jQuery.noConflict(true);
吗?
Obviously if the page already has jQuery loaded. The loading of the 1.3.2 script would overwrite the window.jQuery object on the page. I just wonder is there anyway to let 1.3.2 to load to another self named variable? Using jQuery.noConflict(true);
?
推荐答案
我怀疑您已经了解了所有警告,并了解可以将jQuery移至另一个命名空间:
I suspect you've already seen all the caveats and understand you can move jQuery to another namespace:
//Completely move jQuery to a new namespace in another object.
var dom = {};
dom.query = jQuery.noConflict(true);
该插件可能无法正常工作,您必须在加载或使用其他脚本之前完成所有这些工作.
And that plugins probably won't work AND you must do all this before other scripts are loaded or used.
祝你好运/有点好奇要知道这是否对你有用〜
Good Luck / kinda curious to learn if this works for you~
