Question

Using Babel-Standalone，我正在尝试停用use strict，以便每个the es2015 preset reference使用弃用的with语句。

var code = "with (p) {  // do something }";
var output = Babel.transform(code, { presets: [['es2015', {"loose": true}]] }).code;

这给了我这个错误：

babel.js:17955 Uncaught SyntaxError: unknown: 'with' in strict mode (1:5)

如何使用Babel Standalone禁用严格模式？

Answer 1

答案是parserOpts属性，对应options.js中的Babylon

var output = Babel.transform(code, 
{ 
   presets: ['es2015'], 
   parserOpts: { strictMode: false } 
});

Answer 2

默认情况下，Babel将文件解析为ES6模块。你需要告诉它不要那样做，比如

    <div ng-app="myApp" ng-controller="myCtrl">
    <input ng-model="name">
    <h1>{{name}}</h1><br>
    <p ng-bind="name"></p>
    </div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.name = "John Doe";
});
</script>

禁用＆＃34;使用严格＆＃34;在babel-standalone中
