如何将图像的src绑定到ng-model并将其提取到Angular中? [英] How to bind the src of an image to ng-model and extract it in Angular?

问题描述

我想将一个图像的源绑定到另一个图像的源.

I want to bind the source of an image to the source of another image.

最终结果是，大图像的源应该绑定到所单击的较小(缩略图)图像的src.可以使用ng-model吗?

In the end result, the source of the large image should be bound to the src of the clicked smaller (thumbnail) image. Is this possible using ng-model?

这就是我所拥有的

        <div>
            <img ng-src="{{selectedImg.src}}">
        </div>

        <div>
            <ul ng-repeat="thumb in franchises">
                <li>
                    <img ng-src="{{thumb.images[0].list}}" ng-model="selectedImg">
                </li>
            </ul>
        </div>

推荐答案

您可以使用ng-click来做到这一点:

You could do it using ng-click:

<div>
    <img ng-src="{{selectedImg.src}}" alt="{{slide.images[0].list}}">
</div>

<div>
    <ul ng-repeat="thumb in franchises">
        <li>
            <img ng-src="{{thumb.images[0].list}}" 
                 alt="{{thumb.images[0].list}}" 
                 ng-click="selectedImg.src = thumb.images[0].list" />
        </li>
    </ul>
</div>

但是您必须像这样在控制器中将selectedImg定义为对象:

But you have to define selectedImg as an object in your controller like this:

$scope.selectedImg = {};
