很难调试错误 - 第 2 列的令牌“{"无效键 [英] Having a hard time debugging error - Token '{' invalid key at column 2

问题描述

我遇到了无法调试的错误.

form-field.html

<div class='row form-group' ng-form="{{field}}" ng-class="{ 'has-error': {{field}}.$dirty && {{field}}.$invalid }"><label class='col-sm-2 control-label'>{{ 字段 |labelCase }} <span ng-if='required'>*</span></label><div class='col-sm-6' ng-switch='required'><input ng-switch-when='true' ng-model='record[field][0]' type='{{record[field][1]}}' class='form-control' required ng-change='update()' ng-blur='blurUpdate()'/><div class='input-group' ng-switch-default><input ng-model='record[field][0]' type='{{record[field][1]}}' class='form-control' ng-change='update()' ng-blur='blurUpdate()'/><span class='input-group-btn'><button class='btn btn-default' ng-click='remove(field)'><span class='glyphicon glyphicon-remove-circle'></span></button></span>

<div class='col-sm-4 has-error' ng-show='{{field}}.$dirty &&{{field}}.$invalid' ng-messages='{{field}}.$error'><p class='control-label' ng-message='required'>{{ 字段 |labelCase }} 是必需的.</p><p class='control-label' ng-repeat='(k, v) in types' ng-message='{{k}}'>{{ 字段 |labelCase }} {{v[1]}}</p>

new.html

新联系人</h2>
<form-field record='contact' field='firstName' live='false' required='true'></form-field>
<button class='btn btn-primary' ng-click='save()'>创建联系人</button>
</表单>

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

在有角度的网站上:

<块引用>

错误:$parse:syntax 语法错误语法错误:令牌 '{' 无效键在表达式 [{{field}}.$error] 的第 2 列开始于[{field}}.$error].

有人知道为什么吗?谢谢！

解决方案

我注意到将数据绑定到自定义指令上的属性时也会发生此错误.哪里

$scope.myData.value = "你好！";

这会导致错误:

<my-custom-directive my-attr="{{myData.value}}"></my-custom-directive>

但这工作正常:

<my-custom-directive my-attr="myData.value"></my-custom-directive>

I have encountered an error which I'm unable to debug.

form-field.html

<div class='row form-group' ng-form="{{field}}" ng-class="{ 'has-error': {{field}}.$dirty && {{field}}.$invalid }">
    <label class='col-sm-2 control-label'> {{ field | labelCase }} <span ng-if='required'>*</span></label>
    <div class='col-sm-6' ng-switch='required'>

        <input ng-switch-when='true' ng-model='record[field][0]' type='{{record[field][1]}}' class='form-control' required ng-change='update()' ng-blur='blurUpdate()' />

        <div class='input-group' ng-switch-default>
            <input ng-model='record[field][0]' type='{{record[field][1]}}' class='form-control' ng-change='update()' ng-blur='blurUpdate()' />
            <span class='input-group-btn'>
                <button class='btn btn-default' ng-click='remove(field)'><span class='glyphicon glyphicon-remove-circle'></span></button> 
            </span>
        </div>
    </div>

    <div class='col-sm-4 has-error' ng-show='{{field}}.$dirty && {{field}}.$invalid' ng-messages='{{field}}.$error'>
        <p class='control-label' ng-message='required'> {{ field | labelCase }} is required. </p>
        <p class='control-label' ng-repeat='(k, v) in types' ng-message='{{k}}'> {{ field | labelCase }} {{v[1]}}</p>
    </div>
</div>

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>

I'm getting the following error:

In the browser:

Error: [$parse:syntax] http://errors.angularjs.org/1.4.1/$parse/syntax?p0=%7B&p1=invalid%20key&p2=2&p3=%7B%7Bfield%7D%7D.%24error&p4=%7Bfield%7D%7D.%24error

On angular site:

Error: $parse:syntax Syntax Error Syntax Error: Token '{' invalid key at column 2 of the expression [{{field}}.$error] starting at [{field}}.$error].

Does someone know why? Thanks!

解决方案

I notice that this error also happens when binding data to an attribute on a custom directive. Where

$scope.myData.value = "Hello!";

This causes the error:

<my-custom-directive my-attr="{{myData.value}}"></my-custom-directive>

But this works fine:

<my-custom-directive my-attr="myData.value"></my-custom-directive>
