jquery的eval的使用

eval() 函数可计算某个字符串，并执行其中的的 JavaScript 代码。

<script type="text/javascript">var str="1+2+3";alert(eval(str));
</script>

              <button type="button" id="gfyButton" class="btn btn-info btn-sm" action="querySelect(this,event)">选择</button>;(function($){   debugger;var options = {fieldCode: "gfyId",url: "../../Security/selector/user/PublicServiceUserList.html?s=" + Math.random(),multi: false,code: "gfyId,gfyIdName",keyRespField: "gfyId,id",dictCode: "publicserviceName",area: ['90%','90%']};/*引用查询选择*/function renderSelectorMy(options){debugger;var defaults = {};this.settings = $.extend({},defaults,options);var $domObj = $("#" + this.settings.fieldCode + "-popSelector");this.settings.url = $domObj.attr("action") ? $domObj.attr("action") : this.settings.url;this.settings.multi = $domObj.attr("multi") ? $domObj.attr("multi") : this.settings.multi;this.settings.code = $domObj.attr("codeAndName") ? $domObj.attr("codeAndName").split(",") : this.settings.code.split(",");this.settings.keyRespField = this.settings.keyRespField ? this.settings.keyRespField.split(",") : "";this.init();}//为函数添加原型链上的方法renderSelectorMy.prototype = {init: function(){debugger;var _self = this,_keys = _self.settings.code;$("input[name='" + _keys[0] +"']").parent().parent().find("button").unbind('click').bind('click', function(){var action = "_self." + $(this).attr("action");eval(action);});},querySelect : function(thi,event){debugger;var _self = this;var url = _self.settings.url;var _keys = _self.settings.code;var keyRespField = _self.settings.keyRespField;var id = keyRespField[1];var ids = $("input[name='" + _keys[0] +"']").val();if(url.indexOf("?") != -1) {url = url + "&" + id + "="+ids;}else {url = url + "?" + id + "="+ids;}$Core.UI.openDialog("selwind", url,{title: "列表选择",width: _self.settings.area[0],height: _self.settings.area[1],onClose: function () {}});},echoSelect : function(_data){var _self = this;var data = _data.data,_keys = _self.settings.code,_rkeys = _self.settings.keyRespField,dictName = "",dictCode = _self.settings.dictCode;$Core.DicCache.initDictionary(dictCode,function(dicts){var _dicts = dicts;if(dicts && dicts.data){var dictDatas = dicts.data[dictCode];for(var i=0,len=dictDatas.length; i<len; i++){var item = dictDatas[i];if(data[_keys[0]] == item[_rkeys[1]]){var itemName = item.text;dictName += itemName +",";}}$("span input:text", $("div #" + _keys[0] + "-popSelector")).val(dictName.substr(0,dictName.length-1));}else{$("span input:text", $("div #" + _keys[0] + "-popSelector")).val(dictName);}})},selectResultAfterCallback: function(checkRlt){var _self = this,multi = _self.settings.multi;if(checkRlt.length == 0){$Core.UI.message.warning("选请选择数据!");}if(!multi && checkRlt.length != 1){$Core.UI.message.warning("单选,请选择一条数据!");}var _keys = _self.settings.code,code = "",name = "";if(!_self.settings.multi){code = checkRlt[0]['code'];name = checkRlt[0]['name'];}else{var _code = "",_name = "";for(var i=0,len=dataArr.length; i<len; i++){_code += checkRlt[i]['code'] +",";_name += checkRlt[i]['name'] +",";}code = _code.substring(0,_code.length-1);name = _name.substring(0,_name.length-1);}//给input[name='']:text 赋值address = checkRlt[0]['address'];headPerson = checkRlt[0]['headPerson'];headPersonPhone = checkRlt[0]['headPersonPhone'];customerType = checkRlt[0]['customerType'];$("input[name='address']").val(address);$("input[name='headPerson']").val(headPerson);$("input[name='headPersonPhone']").val(headPersonPhone);/*$("input[name='customerType']").val(customerType);*/$("#customerType").combobox("setValue", customerType);$("input[name='" + _keys[0] + "']:hidden").val(code);$("span input:text", $("div #" + _keys[0] + "-popSelector")).val(name);$(".panel-tool-close").trigger('click');}}  //扩展jquery类方法$.extend({renderSelectorMyf : function(options){return new renderSelectorMy(options);}});
})(jQuery)
debugger;   renderSelector = $.renderSelectorMyf({fieldCode: "gfyId",url: "../../Security/selector/user/PublicServiceUserList.html?s=" + Math.random(),multi: false,code: "gfyId,gfyIdName",keyRespField: "gfyId,id",dictCode: "publicserviceName",area: ['90%','90%']});_self.renderSelectors = [renderSelector];

执行css方法

    _self.listOption.loadSuccess = function(){$(".datagrid-btable tr").find("td[field='gfyId']").css({"text-decoration":"underline","color":"#367fa9"});};
eval(_this.listOption.loadSuccess());
