## jqGrid默认选中行 ##

### 1.确定对比参数列表 ###

var  usernames=["taoql","matea"];

#### 2.loadComplete中添加方法gridSelected() ####

/** * 根据usernames对比选中 */
    function gridSelected(){
        var rowIds = jQuery(grid_selector).jqGrid('getDataIDs');
        for(var k=0; k<rowIds.length; k++) {
           var curRowData = jQuery(grid_selector).jqGrid('getRowData', rowIds[k]);
           for(i=0;i<usernames.length;i++){
               username=usernames[i];
               if(curRowData.username == username){
                   jQuery(grid_selector).setSelection(rowIds[k], false); 
               }
           }
        }
    }

#### 3.属性添加选中事件onSelectRow: onClickWaitRow, ####

/** * 行点击事件 */
    function onClickWaitRow(id,status){
        var curRowData = jQuery(grid_selector).jqGrid('getRowData', id);
        if(!status){
            gridRemoveSelect(curRowData.username);
        }else{
            gridAddSelect(curRowData.username);
        }
    }

#### 4.添加选中、取消事件 ####

/** * 取消选中 */
    function gridRemoveSelect(username){
        usernames.remove(username);
    }
    
    /** * 添加选中 */
    function gridAddSelect(username){
        usernames.push(username);
    }

#### 5.重写Array方法，便于remove ####

/** * 重写Array */
    Array.prototype.remove = function(val) {
        var index = this.indexOf(val);
        if (index > -1) {
        this.splice(index, 1);
        }
    };
    
    /** * 重写Array */
    Array.prototype.indexOf = function(val) {
        for (var i = 0; i < this.length; i++) {
        if (this[i] == val) return i;
        }
        return -1;
    };
