Angular attribute directive that wraps its element

问题

like the title says, I'm attempting to make an attribute directive that wraps its parent and allows me to toggle between editing and showing the actual model value..

In short:

<input ng-model="model" allow-edit="editing" />

Would end up looking like:

<div>
    <div ng-hide="editing">{{model}}</div>
    <input ng-show="editing" ng-model="model"></input>
</div>

If everything went right.

However, I keep on getting something more along the lines of:

<input ng-model="model">
    <!-- html from allow-edit directive's template --!>
</input>

I've used input as an example here, but I'd like to be able to wrap arbitrary content (select, etc) as well...

Has anyone been able to make a directive that wraps other content on the same element? Is there a better way to do this that I'm not considering?

Thanks for your help!

回答1:

What you want to do is replace:true but maintain "=ngModel"

replace:true,
scope:{
  mymodel:"=ngModel",
  editing:"=allowEdit"
}

Heres a Plunker

I hope this answers your question:
In directive options:

1. set replace: true
2. set transclude: "element"
3. use ng-transclude where ever you want to put the original element within the wrapper template.

example:

js:

var app = angular.module("test", []);

app.directive("myCustomInput", function($rootScope){
  return{
    restrict: "A",
    replace: true,
    transclude: "element",
    template: "<div class='input-wrap'>"+
    "<div ng-transclude></div>"+
    "<i class='glyphicon glyphicon-chevron-down'></i>"+
    "</div>"

  }
});

HTML:

<input my-custom-input type="text" />

I think that using replace : true should enable you to replace the original content. Take a look at this StackOverflow answer: Here

If you had a bit more of your directive, I could have a go at getting it to work, but hopefully you can use the plnkr of the other answer to work it out.
