本文介绍了采用NG-重复愚弄时,在角的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我新的角度和NG-重复心不是为我工作。
我的第一个NG-重复的作品,但第二个,其中使用JSON字符串IM不是。它抱怨NG-重复愚弄,但我不明白为什么。什么我哪里做错了?
见code在这里
的jsfiddle
或此:
<!DOCTYPE HTML>
< HTML的xmlns =http://www.w3.org/1999/xhtml>
< HEAD>
<间的charset =UTF-8/>
<标题>测试与LT; /标题>
< /头>
<身体GT; < DIV NG-NG应用程序控制器=AController> < UL>
<李NG重复=项firstTest>
{{项目}}
< /李>
< / UL> <小时/> < UL>
<李NG重复=项secondTest>
{{项目}}
< /李>
< / UL> < / DIV> &所述; SCRIPT SRC =angular.min.js>&下; /脚本> <脚本类型=文/ JavaScript的>
功能AController($范围){
$ scope.firstTest = {
答:123,
B:234
}; $ scope.secondTest ='[{价:123,产品名称:苹果},{价:234,产品名称:鸭梨}]';
}
< / SCRIPT>< /身体GT;
< / HTML>
解决方案
您不能使用JSON直接你反序列化到JSON对象JS如本的的jsfiddle 。
块引用>HTML:
< DIV NG-NG应用程序控制器=AController>
< UL>
<李NG重复=项firstTest>
{{项目}}
< /李>
< / UL>
<小时/>
< UL>
<李NG重复=项secondTest>
{{item.Price}}
< /李>
< / UL>
< / DIV>JS:
函数AController($范围){
$ scope.firstTest = {
答:123,
B:234
}; $ scope.secondTest = JSON.parse('[{价:123,产品名称:苹果},{价:234,产品名称:鸭梨}]');
}I'm new to Angular and ng-repeat isnt working for me.
My first ng-repeat works but the second one where im using a json string isn't. Its complaining about ng-repeat dupes but I dont understand why. What I'm I doing wrong?
see the code here JSFiddle
or here:
<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta charset="utf-8" /> <title>test</title> </head> <body> <div ng-app ng-controller="AController"> <ul> <li ng-repeat="item in firstTest"> {{item}} </li> </ul> <hr /> <ul> <li ng-repeat="item in secondTest"> {{item}} </li> </ul> </div> <script src="angular.min.js"></script> <script type="text/javascript"> function AController($scope) { $scope.firstTest = { a: "123", b: "234" }; $scope.secondTest = '[{"Price": 123,"ProductName": "apple"},{"Price": 234,"ProductName": "pear"}]'; } </script> </body> </html>
解决方案You can not use JSON directly you have to deserialize the JSON to JS Objects as shown in this JSFIDDLE.
HTML:
<div ng-app ng-controller="AController"> <ul> <li ng-repeat="item in firstTest"> {{item}} </li> </ul> <hr /> <ul> <li ng-repeat="item in secondTest"> {{item.Price}} </li> </ul> </div>
JS:
function AController($scope) { $scope.firstTest = { a: "123", b: "234" }; $scope.secondTest = JSON.parse('[{"Price": 123,"ProductName": "apple"},{"Price": 234,"ProductName": "pear"}]'); }
