ng-bind-html不能与我的$ scope.variable一起工作 [英] ng-bind-html not working with my $scope.variable
问题描述
我尝试使用ng-bind-html添加动态HTML,但不能与$ scope变量一起工作
这里是我的Angular代码
1)我的控制器
$ $ p $ $ $ $ c $ $ scope.name =Parshuram
$ scope.thisCanBeusedInsideNgBindHtml = $ sce.trustAsHtml(< div> {{name}}< / div>);
另外,我的字符串是动态的
< div>< table class =+\table table - bordered table - responsive table - hover add - lineheight table_scroll \+>< thead> ;< tr>< td> Name< td>< td> Age< td>< / tr>< / thead>< tbody>< tr ng-repeat = tr in dyna \+>< td> {{tr.name}}< / td>< td> {{tr.age}}< / td>< / tr>< / TBODY>< /表>< / DIV>中
所以我不能用$ scope替换每个变量
2) - My HTML
< div ng-app =mymoduleng-controller =myModuleController> ;
< div ng-bind-html =thisCanBeusedInsideNgBindHtml>< / div>
< / div>
我得到了这个输出
{{name}}
我的预期输出是
Parshuram
请任何人都可以帮助我卡在这一点上,这$ sce不绑定范围变量? ..

问题是ng-bind-html没有绑定到范围。
您应该手动编译内容。
一个有效且可重用的解决方案应该创建一个指令,使用任何外部模块进行清除。
函数compileTemplate($ compile,$ parse){
return {
link:function(scope,element,attr){
var parsed = $ parse(attr.ngBindHtml);
function getStringValue(){return(parsed(scope)||'').toString(); }
范围$ watch(getStringValue,function(){
$ compile(element,null,-9999)(scope);
});
}
}
}
< div ng-app =mymoduleng-controller = myModuleController>
< div ng-bind-html =thisCanBeusedInsideNgBindHtmlcompile-template>< / div>
< / div>
I am trying to add something like dynamic HTML using ng-bind-html but its not working with $scope variable
Here is my Angular code
1)My controller
$scope.name = "Parshuram"
$scope.thisCanBeusedInsideNgBindHtml = $sce.trustAsHtml("<div>{{name}}</div>");
Also that my string is dynamic
"<div><table class=" + "\"table table - bordered table - responsive table - hover add - lineheight table_scroll\"" + "><thead><tr><td>Name</td><td>Age</td></tr></thead><tbody><tr ng-repeat=" + "\"tr in dyna\"" + "><td>{{tr.name}}</td><td>{{tr.age}}</td></tr></tbody></table></div>"
So i cant replace every variable with $scope
2)- My HTML
<div ng-app="mymodule" ng-controller="myModuleController">
<div ng-bind-html="thisCanBeusedInsideNgBindHtml"></div>
</div>
I got this output
{{name}}
My expected output is
Parshuram
Please can anyone help i am stuck at this point,does that $sce does not bind scope variable?? ..
I've created a working plnkr here: https://plnkr.co/edit/uOdbHjv1B7fr0Ra1kXI3?p=preview
the problem is that ng-bind-html is not bound to the scope. you should manually compile the content.
a valid and reusable solution should be creating a directive, whitout using any external modules.
function compileTemplate($compile, $parse){
return {
link: function(scope, element, attr){
var parsed = $parse(attr.ngBindHtml);
function getStringValue() { return (parsed(scope) || '').toString(); }
scope.$watch(getStringValue, function() {
$compile(element, null, -9999)(scope);
});
}
}
}
<div ng-app="mymodule" ng-controller="myModuleController">
<div ng-bind-html="thisCanBeusedInsideNgBindHtml" compile-template></div>
</div>
