AngularJS自定义标签添加回调函数eval()

来源：互联网发布：媒体姓党魂归大海知乎编辑：程序博客网时间：2024/06/10 20:51

function helloworld(name){ console.log("hello!!!!!"+name)} var name="zhangsan";eval("helloworld(name)");

代码粘贴到谷歌的控制台可以看到

hello!!!!! zhangsan

可以使用这个功能----返回用户选择的某行数据。

<smcs-search-input-table table-uniqueflag="b" table-resultjson="jsonresulta" table-showcols="showtablecolsa"  table-temprow="6" table-querycol="0,1" table-outcol="0" table-callback="gettabledata(data)" resultcache="true" ></smcs-search-input-table>

gettabledata(data)是用户自定义函数。我会在directive封装标签的里面调用这个行数，把用户选择的某行数据以json对象返回给data.

</pre><pre name="code" class="javascript">//双击某行时，把选中的数据输出 $scope.selectRow = function (id){if(id==1){return;//标题行}var trtdid="#"+tableuniqueflag+""+id+(parseInt(tableoutcol)+1);//取idvar trtdval=$(trtdid).text();//取值var trtdidarray=new Array();//<td>id数组//trtdidarray = ["#b41", "#b42", "#b43"]var trtdvalarray=new Array();//<td>中内容数组//trtdvalarray=["a王武", "男", "北京"]for(var i=0;i<cells;i++){trtdidarray[i]="#"+tableuniqueflag+""+id+(parseInt(i)+1);//表格一行的数据trtdvalarray[i]=$(trtdidarray[i]).text();}console.log(colattrs);//colattrs=["testname", "sex", "addr"]//json格式 { "testname": "a张三", "sex": "男","addr":"天津","tel":"138"}data="{"for(var j=0;j<cells;j++){data=data+'\"'+colattrs[j]+'\"'+":"+'\"'+trtdvalarray[j]+'\"';if(j<(cells-1)){data=data+","}}data=data+"}"//调用用户再app.controller中定义的回调函数。$scope.tablecallbackfun(JSON.parse(data));//把选中的项填写到输入框document.getElementById("inputable"+tableuniqueflag).value = trtdval;$(mydivlocation).css('display','none');} //选中某行并将值的字符串返回父页面$scope.tablecallbackfun = function(data){eval("$scope."+tablecallback);}

app.controller

(function(){var app = angular.module('SMCS.App');app.controller('MedicareInstitutionInfoMaintainCtrl', ['$scope','$http', 'BaseURL','$modal','Modal',function($scope,$http,BaseURL,$modal,Modal){//后台返回数据$scope.jsonresulta = [{ "testname": "a张三", "sex": "男","addr":"天津","tel":"138"},{ "testname": "a张狗", "sex": "男","addr":"上海","tel":"138"},{ "testname": "a王武", "sex": "男","addr":"北京","tel":"138"},{ "testname": "a张武", "sex": "男","addr":"北京","tel":"138"},{ "testname": "a花木兰", "sex": "女","addr":"北京","tel":"138"}];$scope.showtablecolsa = [{ label: '姓名', map: 'testname'},{ label: '性别', map: 'sex'},{ label: '住址', map: 'addr'}];$scope.gettabledata = function(data){//data json对象，可以取里面的属性,相比原来返回一个值更灵活console.log("sex==="+data.sex);}}]);})()
