  • select帮助类,批量绑定slect

    这边只写了前端的绑定,后端绑定放在C#部分。

    select绑定html

    <select name="OrderStatusID" id="OrderStatusID" selectjson='{"ServiceName":"Order","HandlerMethod":"GetOrderTableMappingList","parameterDataJsonString":"{"modelParam":{"MappingType":"2"}}"}'
        bindjson='{"value":"ID","html":"TableMappingName","isAll":true,"parentValue":"PlatformID","isParentContain":true,"allHtml":"请选择"}'>
    </select>

    调用select帮助类js

    //获取需要绑定对象集合
    configData = {
      url: "",
       formID:""
    };
    //在封闭的空间,传到全局变量
    window.dataSourceList
    = CommonFormHelper.GetSelectDataSource(configData); //绑定select对象 CommonFormHelper.SetSelectHtmlByDataSourceList(dataSourceList);

    select绑定js:CommonFormHelper

        Settings: {

                };
            };
        },
        Load: function () { },
        GetSelectDataSource: function (settings) {

            settings.async = false;
            settings.data = { dataSourceSettingsList: CommonFormHelper.GetFormSelectJsonDataByName(settings.formID) };
