<div class='row form-group' ng-form="{{field}}" ng-class="{ 'has-error': {{field}}.$dirty && {{field}}.$invalid }">

new.html
<h2> New Contact </h2>
<form name='newContact' novalidate class='form-horizontal'>
<form-field record='contact' field='firstName' live='false' required='true'></form-field>
<div class='row form-group'>
<div class='col-sm-offset-2'>
<button class='btn btn-primary' ng-click='save()'> Create Contact </button>
</div>
</div>
</form>
我收到以下错误:
在浏览器中:
错误:[$ parse:syntax]
http://errors.angularjs.org/1.4.1/ $ parse / syntax?p0 =%7B& p1 = invalid%20key& p2 = 2& p3 =%7B%7Bfield%7D%7D。%24error& p4 =%7Bfield%7D%7D。%24error

在角度站点上:
错误:$ parse:syntax语法错误语法错误:令牌'{'无效键
at表达式[{{field}}。$ error]的第2列,起价为
[{field}}。$ error]。
Error: $parse:syntax Syntax Error Syntax Error: Token '{' invalid key at column 2 of the expression [{{field}}.$error] starting at [{field}}.$error].
有人知道为什么吗?谢谢!
Does someone know why? Thanks!
推荐答案
我注意到在将数据绑定到自定义指令的属性时也会发生此错误。其中
I notice that this error also happens when binding data to an attribute on a custom directive. Where
$scope.myData.value = "Hello!";
这会导致错误:
<my-custom-directive my-attr="{{myData.value}}"></my-custom-directive>
但这样可行:
<my-custom-directive my-attr="myData.value"></my-custom-directive>
