使用easyui combobox初始化+在input中触发下拉框+获取值

效果图：

1.html

1	`<input id="alarmLeve"` `class="easyui-combobox"` `name="alarmLeve"` `style="width:100px;display:inline-block;margin-right:20px;"/>`

2.js

//初始化
$('#alarmLeve').combobox( { 
    multiple: true,
    panelHeight: 'auto',//自适应
    valueField: 'id',//绑定字段ID
    textField: 'text',//绑定字段Name
    onLoadSuccess:function(){
        $(".combo").click(function(){
                 $(this).prev().combobox("showPanel");
       });
   },
    data:[{
        "id":1,
        "text":"1"
    },{
        "id":2,
        "text":"2"
    },{
        "id":3,
        "text":"3"
    },{
        "id":4,
        "text":"4"
    }],
    formatter: function (row) {
        var opts = $(this).combobox('options');
        return '<input type="checkbox" class="combobox-checkbox" style="margin:0 5px;vertical-align: -2px" id="' + row[opts.valueField] + '">' + row[opts.textField]
    },
    //获取数据URL  
    //选择树节点触发事件  
    onSelect: function (row) {
        var opts = $(this).combobox('options');
        var el = opts.finder.getEl(this, row[opts.valueField]);
        el.find('input.combobox-checkbox')._propAttr('checked', true);
    },
    onUnselect: function (row) {
        var opts = $(this).combobox('options');
        var el = opts.finder.getEl(this, row[opts.valueField]);
        el.find('input.combobox-checkbox')._propAttr('checked', false);
    }
})
