我是角度指示模块的新手。
如果我在我的指令定义中使用transclude并将其设置为true,我实际上可以在编译时在指令模板中添加一个额外的html模板。
请按照以下代码
<!DOCTYPE html>
<html lang="en">
<head>
<title>Chapter-01 example 15</title>
<script type="text/javascript" src="D:\Rahul Shivsharan\JavaScript-Framework\AngularJS\angular.js"></script>

<script type="text/javaScript">
angular.module("MyApp",[]);
(function(){
angular.module("MyApp").controller("MyCtrl",MyCtrl);
angular.module("MyApp").directive("simpleDirective",simpleDirective);
function MyCtrl($scope){
$scope.myCtrlObj = new Object();
$scope.myCtrlObj.localName = "John Wayne";
$scope.myCtrlObj.petName = "Johny";
};
function simpleDirective(){
var templatStr = "<div class='alert alert-warning'>"+
"<h3>This is Toggle Example....</h3>" +
"<h2><strong>{{myCtrlObj.localName}}</strong></h2>"+
"</div>";
return {
restrict : "EA",
template : function(tElem,tAttr){
return templatStr;
},
replace : true,
transclude : true ,
link : function(scope,elem,attr,controller,transcludeFn){
scope.myCtrlObj.localName = "Leonardo Di Caprio";
scope.myCtrlObj.petName = "Leo";
scope.showMe = function(){
if (elem.hasClass("alert-success") === true){
elem.removeClass("alert-success");
elem.addClass("alert-warning");
}else{
elem.removeClass("alert-warning");
elem.addClass("alert-success");
}
};
var clonedElement = transcludeFn(function(clone){
return clone;
});
elem.append(clonedElement);
}
}
}
})();
</script>
</head>
<body>
<div ng-app="MyApp" ng-controller="MyCtrl" class="container">
<div class="page-header">
<h3>This is Directive Practise</h3>
</div>
<div class="row">
<div class="col-md-4">
<input type='button' class='btn btn-primary' value="Click-Me" ng-click='showMe()' />
</div>
</div>
<div class="row" style="margin-top:2%">
<div class="col-md-4">
<div simple-directive>
<span>His real Name is : <b>{{myCtrlObj.localName}}</b><span>
<br/>
<span>His pet name is : <b>{{myCtrlObj.petName}}</b></span>
</div>
</div>
</div>
</div>

工作正常, 我正在粘贴上面代码的工作示例链接 Working example of above code
现在我在上面的代码中做了一些更改,比如,
按如下方式更改链接功能,
link : function(scope,elem,attr,controller){
scope.myCtrlObj.localName = "Leonardo Di Caprio";
scope.myCtrlObj.petName = "Leo";
scope.showMe = function(){
if (elem.hasClass("alert-success") === true){
elem.removeClass("alert-success");
elem.addClass("alert-warning");
}else{
elem.removeClass("alert-warning");
elem.addClass("alert-success");
}
};
}
在上面的代码中,我删除了从tranclude函数返回的clone的附加元素。
将ng-transclude添加到模板中,如下所示,
var templatStr = "<div class='alert alert-warning'>"+
"<h3>This is Toggle Example....</h3>" +
"<h2><strong>{{myCtrlObj.localName}}</strong></h2>"+
"<ng-transclude></ng-transclude>" +
"</div>";
通过执行上述所有更改,不会附加html模板。

我读过的是如果我们在模板中使用ng-transclude,我们不需要在链接中编写transclude函数,
如果是,为什么我的第二个例子不起作用。
答案 0 :(得分:0)
您需要更改以下内容
<ng-transclude></ng-transclude>
要
<div ng-transclude></div>
它会发挥作用。原因是您使用的角度版本不支持使用 ng-transclude 作为元素。
