如何更改“材料设计"按钮行中所选按钮的外观? [英] How do I change the appearance of the selected button in a row of Material Design buttons?

问题描述

我有一个HTML表，在几行中，每个单元格中都有一个Material Design按钮，该按钮是使用AngularJS动态生成的.

I have a HTML table and in several rows I have a Material Design button in each cell, dynamically generated using AngularJS.

<table class="plans">
    <tbody>
        <tr>
            <td>Work Plans</td>
            <td ng-click="pbmainController.selectPlan(plan.planName)"
                ng-repeat="plan in pbmainController.planList">
                    <md-button class="md-raised">{{plan.planName}}</md-button>
            </td>
        </tr>
    </tbody>
</table>

一次只能选择一个按钮(即单选按钮).

Only one of button can be selected at a time (i.e. like a radio button).

如何更改所选按钮的颜色?

How do I change the color of the selected button?

推荐答案

我通过使用三元运算符将ng-class放在按钮上来使其工作

I got it to work by putting the ng-class on the button, using the ternary operator

<table class="plans">
    <tbody>
        <tr>
            <td>Work Plans</td>
            <td ng-click="pbmainController.selectPlan(plan.planName)"
                ng-repeat="plan in pbmainController.planList">
                    <md-button ng-class="plan.planName == selectedPlanName ? 'md-raised md-primary' : 'md-raised'">{{plan.planName}}</md-button>
            </td>
        </tr>
    </tbody>
</table>
