一段js代码求解
哥哥你也把代码给缩进一下啊，看着好累的
Mgly.diff = function (lhs, rhs, options){
var opts = jQuery.extend({
ignorews : false
}, options);
this.codeify = new Mgly.CodeifyText({
lhs : lhs,
rhs : rhs,
options : opts
});
var lhs_ctx = {codes : this.codeify.getCodes('lhs'),modified : {}};
var rhs_ctx = {codes : this.codeify.getCodes('rhs'),modified : {}};
var max = (lhs_ctx.codes.length + rhs_ctx.codes.length + 1);
var vector_d = Array(2 * max + 2);
var vector_u = Array(2 * max + 2);
this._lcs(lhs_ctx, 0, lhs_ctx.codes.length, rhs_ctx, 0, rhs_ctx.codes.length, vector_u, vector_d);
this._optimize(lhs_ctx);
this._optimize(rhs_ctx);
this.items = this._create_diffs(lhs_ctx, rhs_ctx);//items中存放创建的差异信息
};
还有你的代码没有复制齐全。很多方法没有复制过来
js的一段代码解读
JS也有面向对象的。
上面定义的function其实在定义一个对象
下面使用的newemp=new employee("zhangming",'A002');
其实在创建一个对象，并且将对象的属性赋值
然后输出的时候，当然是对象的属性值了
JS创建对象，你还需要多了解一些的。并不像JAVA那样明显
了解多了，看起来就明显了

Js编程语言中，自调用函数是什么？举个Js代码例子解释一下！
自调用函数：
顾名思义，有2个意思
《1》自行调用的函数：
就是指，函数在页面载入后或者之前就自行调用，无需借助其他函数或方法来启动；
例如：
(function(win){
win.alert(11);
})(window);
《2》自己调用自己的函数：
就是指，递归：在一个函数里面调用自己的函数，当符合一定规则时，跳出自我调用，就是递归。
例如：
var fn = function(n){
if(n == 1) return 1;
else return n * fn(n-1);
}
求一段JS代码！鼠标离开文本框后提交数据！
form name="from1"
input type="text" name="txt1" id="txt1" onblur="getVal(this.id)" /
input type="text" name="txt2" id="txt2" onblur="getVal(this.id)" /
/form
script type="text/javascript"
function getVal(id)
{
alert(document.getElementById(id).value);
}
/script
注：onblur事件是在失去焦点的时候，不知道符不符合你的要求
你还可以试试onmouseout，鼠标一移出文本框就触发
