一段js代碼求解
哥哥你也把代碼給縮進一下啊，看著好累的
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中存放創建的差異信息
};
還有你的代碼沒有複製齊全。很多方法沒有複製過來
js的一段代碼解讀
JS也有面向對象的。
上面定義的function其實在定義一個對象
下面使用的newemp=new employee(“zhangming”,’A002′);
其實在創建一個對象，並且將對象的屬性賦值
然後輸出的時候，當然是對象的屬性值了
JS創建對象，你還需要多了解一些的。並不像JAVA那樣明顯
了解多了，看起來就明顯了

Js編程語言中，自調用函數是什麼？舉個Js代碼例子解釋一下！
自調用函數：
顧名思義，有2個意思
《1》自行調用的函數：
就是指，函數在頁面載入後或者之前就自行調用，無需藉助其他函數或方法來啟動；
例如：
(function(win){
win.alert(11);
})(window);
《2》自己調用自己的函數：
就是指，遞歸：在一個函數裡面調用自己的函數，當符合一定規則時，跳出自我調用，就是遞歸。
例如：
var fn = function(n){
if(n == 1) return 1;
else return n * fn(n-1);
}
求一段JS代碼！滑鼠離開文本框後提交數據！
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
註：onblur事件是在失去焦點的時候，不知道符不符合你的要求
你還可以試試onmouseout，滑鼠一移出文本框就觸發
