jquery 冲突问题求解

[lbkbox]

各位同仁：您们好，有个问题求高仁解答：
我有两个js文件common.js和jquery-1.7.2.js 产生冲突了，我按网上的把common.js里的$改成了jq，然后在所有引用到common.js的地方都把$改成了jq ,可是还是冲突，我发现，如果把common.js里的这段代码：

Object.prototype.extend = function(a) {
return Object.extend.apply(this, [this, a])
};

注销掉，jquery-1.7.2.js 正常使用，但这段代码注销掉，则common.js 功能就不能用了，求解？
下面贴出 common.js 源码如下：

var Class = {
create: function() {
return function() {
this.initialize.apply(this, arguments)
}
},
inherit: function(a, b, c) {
Object.extend(Object.extend(a.prototype, b.prototype), c)
}
};

Object.extend = function(a, b) {
for (property in b) a[property] = b[property];
return a
};
//就是如下一句冲突
Object.prototype.extend = function(a) {
return Object.extend.apply(this, [this, a])
};

Function.prototype.bind = function(a) {
var b = this;
return function() {
return b.apply(a, arguments)
}
};
Function.prototype.bindAsEventListener = function(a) {
var b = this;
return function(c) {
b.call(a, c || window.event)
}
};
Number.prototype.toColorPart = function() {
var a = this.toString(16);
return 16 > this ? "0" + a: a
};
var Try = {
these: function() {
for (var a, b = 0; b < arguments.length; b++) {

Object.prototype.extend = function(a) {
return Object.extend.apply(this, [this, a])
};

重命名

[lbkbox]

重命名 我也想到了，我把： Object.prototype.extend = function(a) { return Object.extend.apply(this, [this, a]) }; 命名成： Object.prototype.ddddd = function(a) { return Object.extend.apply(this, [this, a]) }; 也行不行，还是冲突，而我命名成这样： Object.xxxxx.extend = function(a) { return Object.extend.apply(this, [this, a]) }; jquery 可以了，但common.js功能失效了。 难道是：Object.prototype 与 jquery 中的Object.prototype 冲突？

[程序员鼓励师]

调整顺序，先加载common.js，再加载jquery.js 紧跟着，声明一下var jq = jQuery.noConflict(); 最后，自己js里的$替换成jq 完整例子 <script type="text/javascript" src="js/common.js"></script> <script type="text/javascript" src="js/jquery-1.7.2.js"></script> <script type="text/javascript"> var jq = jQuery.noConflict(); </script>

[lbkbox]

谢谢，我也调整过顺序，先加载common.js，再加载jquery.js 应该不是$符号冲突吧，因为我把common.js中的$和用到common.js中的$都改成了jq

[lbkbox]

这到底是什么原因？，有人帮我解决吗？
