推薦：關(guān)于php循環(huán)跳出的問(wèn)題
本篇文章是對(duì)php中循環(huán)跳出的問(wèn)題進(jìn)行了詳細(xì)的分析介紹，需要的朋友參考下 復(fù)制代碼 代碼如下: //php當(dāng)前循環(huán)為1，循環(huán)由里到外依次遞增，break默認(rèn)為1，例如跳出第2層循環(huán) for ($i=0;$i3;$i++){ foreach (array(1,2,3) as $val){ foreach (array(1,2,3) as $val){ echo

最近調(diào)試EXTJS 4的treegrid實(shí)例，看了很多水友的文章，以及官方的demo， 沒(méi)一個(gè)可靠的，全都無(wú)法顯示出來(lái)。像對(duì)于我們習(xí)慣用C++的coder來(lái)說(shuō)，EXTJS簡(jiǎn)直就是一群無(wú)政府土匪來(lái)維護(hù)的，官網(wǎng)上連個(gè)搜索框都沒(méi)有，找資料基本靠遍歷，還是人工的。

使用treegrid，需要在調(diào)用頁(yè)面的head中加載以下幾個(gè)文件：

復(fù)制代碼 代碼如下:
<link rel="stylesheet" type="text/css" href="css/ext-all.css">
<script type="text/javascript" src="ext-all.js"></script>
<script type="text/javascript" src="treegrid.js"></script>

然后在頁(yè)面的body中寫(xiě)上一個(gè)div

復(fù)制代碼 代碼如下:
<div id="tree-example"></div>

以上官方就這么寫(xiě)的，BUT，蛋疼的是，JS里沒(méi)有改，不改就沒(méi)法運(yùn)行成功。把treegrid.js中的renderto，改成我們的div的ID就行了。

記得把json數(shù)據(jù)文件和css文件等拷貝到調(diào)用目錄下。
完成的treegrid.js代碼為：

復(fù)制代碼 代碼如下:
