可以在AngularJs中设置基本标签的href属性? [英] It is possible to set the href attribute of a base tag in AngularJs?
问题描述
我想根据常量值设置 href
属性值 base
标签。为此,我已经在头
元素中声明了 base
属性,如下所示:
< head>
< base ng-href ={{baseUrl}}>
< / head>
,我用这个设置了 baseUrl
代码片段:
app.run([$ rootScope,env),function($ rootScope,env){
$ rootScope.baseUrl = env.baseUrl;
}]);
其中 env
是角度常数。 / p>
locationProvider
以这种方式配置:
.config(function($ locationProvider){
$ locationProvider.html5Mode(true);
})
当我运行它时,我看到正确设置的值:
< base ng-href =/href =/>
但在控制台中我收到此错误:
错误:[$ location:nobase] $位置在HTML5模式下需要< base>标签要存在!
http://errors.angularjs.org/1.3.14/$location/nobase

如果我直接设置href属性,而没有ngHref:
< base href ={{baseUrl}}>
我收到此错误:
错误:无法在历史记录上执行replaceState:无法在原始文件http:// localhost中创建具有URLhttp:// items /的历史状态对象: 9000'。

其中项目
是默认路由路径:
.otherwi se({
redirectTo:'items'
});
在JavaScript中设置基础,然后进行手动引导:
/ *创建基元* / var base = document.createElement('基础'); / *创建脚本元素* / var script = document.createElement('script'); / *设置基础href * / base.href =http://example.com; / *设置脚本src * / script.src =http://ajax.googleapis.com/ajax/libs/angularjs/1.3.1/angular.min.js; / *将基本标签附加到body * / document.getElementsByTagName(body)[0] .appendChild(base); / *将脚本标签附加到头部* / document.getElementsByTagName(head)[0] .appendChild(script);函数html5Mode($ locationProvider){$ locationProvider.html5Mode(true); };函数dothis(){// template string var html =< div> ID:{{$ id}}阶段:{{$$ phase}}被破坏:{{$$ destroyed}} listeners:{{$$ listeners }} root:{{$ root}}< / div>; // template object var template = angular.element(html); // template transformer var compiler = angular.injector([ng])。get($ compile); // template result var links = compiler(template); // scope object var scope = angular.injector([ng])。get($ rootScope); // scope binding var result = linker(scope)[0]; / *将结果附加到body * / document.body.appendChild(result); / *渲染* / angular.bootstrap(document,['ng',html5Mode]); } script.onload = dothis;

I want to set the href
attribute value of base
tag based on a constant value. To do so I've declared the base
attribute in the head
element as follows:
<head>
<base ng-href="{{baseUrl}}">
</head>
and I set the baseUrl
value with this code snippet:
app.run(["$rootScope","env", function($rootScope, env){
$rootScope.baseUrl = env.baseUrl;
}]);
where env
is the Angular constant.
The locationProvider
is configured in this way:
.config(function ($locationProvider) {
$locationProvider.html5Mode(true);
})
When I run it I see the value set correctly:
<base ng-href="/" href="/">
but in the console I get this error:
Error: [$location:nobase] $location in HTML5 mode requires a <base> tag to be present!

If I set the href attribute directly without ngHref:
<base href="{{baseUrl}}">
I get this error:
Error: Failed to execute 'replaceState' on 'History': A history state object with URL 'http://items/' cannot be created in a document with origin 'http://localhost:9000'.

Where items
is the default routing path:
.otherwise({
redirectTo: 'items'
});
Set the base in JavaScript, then do manual bootstrapping:
/* Create base element */
var base = document.createElement('base');
/* Create script element */
var script = document.createElement('script');
/* Set base href */
base.href = "http://example.com";
/* Set script src */
script.src = "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.1/angular.min.js";
/* Append base tag to body */
document.getElementsByTagName("body")[0].appendChild(base);
/* Append script tag to head */
document.getElementsByTagName("head")[0].appendChild(script);
function html5Mode ($locationProvider)
{
$locationProvider.html5Mode(true);
};
function dothis()
{
//template string
var html = "<div>ID: {{$id}} Phase: {{$$phase}} Destroyed: {{$$destroyed}} listeners: {{$$listeners}} root: {{$root}}</div>";
//template object
var template = angular.element(html);
//template transformer
var compiler = angular.injector(["ng"]).get("$compile");
//template result
var linker = compiler(template);
//scope object
var scope = angular.injector(["ng"]).get("$rootScope");
//scope binding
var result = linker(scope)[0];
/* Append result to body */
document.body.appendChild(result);
/* Render */
angular.bootstrap(document, ['ng', html5Mode]);
}
script.onload = dothis;
