combobox 的onLoadSuccess执行两次解决办法和 取值赋值

加红色字部分

jsp

<input class="easyui-combobox" id="keshi" name="keshi" value="${tPetitionReport.keshi}" />

js

整体关键代码示例如下：

　　

$('#keshi').combobox({
    url: '/ccewis/xffy/keshiList',
    valueField: 'id',
    textField: 'groupName',
    multiple:true,
    //width:tableWidth*0.17,
    editable: true,
    filter: function (q, row) {
        var opts = $(this).combobox("options");
        return row[opts.textField].indexOf(q) > -1;//将从头位置匹配改为任意匹配
    },
    onLoadSuccess: function () {  //下拉框数据加载成功调用 
        var values = $(this).combobox('getValues').join(',');//获取选中的值的values
        $(this).combobox('setValues',values.split(','));    //http://www.verydemo.com/demo_c110_i7529.html

    },
    onSelect: function (rec) {
        var keshiId = encodeURIComponent(rec.id);
        //$('#visibleMan').combobox('clear');
        $('#visibleMan').combobox('reload', '/ccewis/xffy/userList?keshiId=' + keshiId);
    },
    onChange: function (newValue, oldValue) {
        if (newValue == "") {
            $('#visibleMan').combobox('clear').combobox('reload', '/ccewis/xffy/userList');
        }
    }
});
