利用javaScript实现点击输入框d出窗体选择信息_javascript技巧

复制代码 代码如下:

//数组信息

var arrs = new Array();

arrs.push({id:"1", name:"张三3"});

arrs.push({id:"2", name:"李四3"});

arrs.push({id:"3", name:"申午武3"});

arrs.push({id:"4", name:"周琬淞3"});

arrs.push({id:"5", name:"覃晓为3"});

arrs.push({id:"6", name:"王五"});

arrs.push({id:"7", name:"宝典3"});

/**

* obj: 点击文本框的对象

* idStr: json数组的id键名

* nameStr: json数组的name键名

* bool: true:表示追加 false:表示重新赋值

* boolSet: true:ID和Name的值都显示 false:只显示Name的值

* widthNum: 信息DIV的宽度

* heightNum: 信息DIV的高度

* arrName: 数组名称

*/
