HTML：使链接可编辑

Question

I have an angular page that I display a series of links on from a list. Here's the HTML/Angular code:

<li role="menuitem"
    ng-repeat="foo in foos track by $index"
    ng-click="selectFoo(foo)">
    <a href="#">
        {{foo}}
        <span class="glyphicon glyphicon-pencil pull-right"></span>
    </a>
</li>

I want the user to be able to edit the display name of foo by clicking on the glyphicon. I could do this pretty easily by adding an ng-click component to the <span> and opening up a modal with a text input etc etc.

But I want to do it in a more streamlined manner. Is it possible to have the glyphicon click change the link into a text input where the user can type something, hit enter and finish editing. I don't want to make the <a> into a text input because clicking on it does another action. Is there any way to achieve what I want?

Answer 1

You could use AngularJS to switch between showing {{foo}} and showing an <input> that is binded to foo :

<li role="menuitem"
    ng-repeat="foo in foos track by $index">
  <span data-ng-hide="foo.isEditing" data-ng-model="foo"></span>
  <input type="text" data-ng-show="foo.isEditing" data-ng-model="foo">
  <a data-ng-click="foo.isEditing = !foo.isEditing" href="#">
    <span class="glyphicon glyphicon-pencil pull-right"></span>
  </a>
</li>

So when a user clicks the glyphicon then it should toggle the state of foo.isEditing from false to true or vice-versa. Both span and input are binded to foo via ng-model so updates to foo happen instantaneously. Let me know if this works out for ya, cheers!

Setting the contentEditable property on your targeted span element should be the simplest solution one may desire. eg:

<span class="glyphicon glyphicon-pencil pull-right" contentEditable="true"></span>

Also, controlling it (most probably by implementing an on/off toggle ) through your script, would be as easy.
