ExtJs4(3)——带搜索和操作按钮的表

带搜索和操作按钮的表（这里的问题是，下面由两条框框，不知怎么去掉，浪费不少空间也影响了美观。）

点击：

修改按钮：将弹出此窗口

详细按钮：与修改按钮相同，但保存按钮为不可能状态（即不能保存，只能查看）

新增按钮：与修改按钮相同，但里面没有数据

带搜索功能的表格已经在前文写过，在此便不再赘述。本文的要点是如何为表格添加对应的弹出窗口。

弹出窗口一般由两部分组成，一部分是外面的Window，另外一部分则是嵌入在Window里的与Grid的Columns想对应的内容

一般来说可以这样写：

ModifyWin = Ext.extend(Ext.util.Observable,{
     alertWin : null,		/* 弹出窗口 */
     alertPanel : null,		/* 弹出Panel */
     field : null,   		/* 放置弹出窗口内使用的变量 */

     constructor:function() {
	this.alertPanel = new MyFormPanel; //MyFormPanel是与表格Columns对应的Panel
	this.alertWin = Ext.create('Ext.window.Window', {
	    //别的一些属性
	    items: this.alertPanel
        }
     }
});

这样，便可以用一个变量modifyWin= New ModifyWin来产生一个实例作为缓存，而不需要每次弹出窗口时重新初始化一个窗口。

全部代码：

pageVar.js

var pageVar={};
//--------------------------弹出窗口的设置-----------------------------
pageVar.SRC_LOC_Y = 5;		//Panel中item项的起始点的x
pageVar.SRC_LOC_X = 5;		//Panel中item项的起始点的y
pageVar.EACH_DIST_Y = 30;	//上下两个Item之间的距离
pageVar.FIELD_WIDTH = 60;	//item项的默认长度
pageVar.vWidth=210;         //标签的整体宽度
pageVar.vFieldW=210;        //标签空白内容的宽度
pageVar.LABEL_WIDTH = 70;	//item项的标签的默认宽度
pageVar.vOneLineWidth = 2 * pageVar.vWidth;                 //一行只放置一个标签时，标签的长度
pageVar.vPanelW = pageVar.vOneLineWidth + 65;


//--------------------与grid相关的参数设置--------------------

pageVar.gridTitle = 'sysLogPanel';               //表的标题

pageVar.ajaxRequestUrl = 'grid.json'               //连接ajax的url

pageVar.modelName = 'sysLog';

pageVar.rootName = 'sysLog';

pageVar.gridStoreUrl = 'sysLog.json';   //表的Store的url

//其中数字1代表有效，0代表无效
pageVar.bButtons = [ 0, 1, 0, 0 ];              //bButtons[0]为添加按钮，bButtons[1]为修改，bButtons[2]为查询，bButtons[3]为删除;
