Extjs4 Treegrid 使用心得分享(經驗篇)_PHP教程
推薦:關于php循環跳出的問題本篇文章是對php中循環跳出的問題進行了詳細的分析介紹,需要的朋友參考下 復制代碼 代碼如下: //php當前循環為1,循環由里到外依次遞增,break默認為1,例如跳出第2層循環 for ($i=0;$i3;$i++){ foreach (array(1,2,3) as $val){ foreach (array(1,2,3) as $val){ echo
最近調試EXTJS 4的treegrid實例,看了很多水友的文章,以及官方的demo, 沒一個可靠的,全都無法顯示出來。像對于我們習慣用C++的coder來說,EXTJS簡直就是一群無政府土匪來維護的,官網上連個搜索框都沒有,找資料基本靠遍歷,還是人工的。
使用treegrid,需要在調用頁面的head中加載以下幾個文件:
<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>
然后在頁面的body中寫上一個div
<div id="tree-example"></div>
以上官方就這么寫的,BUT,蛋疼的是,JS里沒有改,不改就沒法運行成功。把treegrid.js中的renderto,改成我們的div的ID就行了。
記得把json數據文件和css文件等拷貝到調用目錄下。
完成的treegrid.js代碼為:
