Tips for dynamically adjusting the style of table rows in a v-for iteration:

I'm trying to dynamically change the background color of a table row within a v-for loop based on a condition - if global.globalGroupLevel is equal to 0, I want the background color to be one color, and if it's not 0, I want it to be another color. I know I could achieve this by duplicating the table row and using v-if and v-else directives, but that would make my code look messy. Another option I considered was using a ternary operator directly on the tr element to set the style, but I'm unsure if this is possible and how I would go about doing it.

Currently, part of my code looks like this:

<tbody>
    <template v-for="global in orderItems">
        <tr>
            ... A bunch of code
        </tr>
    </template>
</tbody>

As mentioned before, I could do something like this:

<tbody>
    <template v-for="global in orderItems">
        <tr :style="{background: global.globalGroupLevel == 0 ? '#ccc' : 'white'}">
            ... Bunch of code
        </tr>

    </template>
</tbody>

However, this approach feels overly complicated for something as simple as changing the background color of a table row. Are there any better options available to accomplish what I need?

Answer №1

To achieve the desired outcome, you have two options: You can implement a solution utilizing a class as suggested in a previous response, or you can utilize :style as per your requirement:

:style="{ background: global.globalGroupLevel == 0 ? '#ccc' : 'white' }"

Answer №2

Start by defining two distinctive classes named whitebg and graybg. Then, utilize the class binding technique in the following manner:

  <tr v-bind:class="{ global.globalGroupLevel == 0? 'graybg' : 'whitebg'}"></tr>

Incorporate the corresponding CSS rules to style these classes:

 .whitebg{
    background:white
    }
 .graybg{
    background:#ccc
 }

Answer №3

It is considered a best practice to avoid using inline styles and instead keep CSS within its dedicated tag.

To achieve this, you can add a class:

<tr :class="['gray-group', { 'white-group': global.globalGroupLevel }]"></tr>

Then, apply the following CSS:

tr.gray-group {
  background: #ccc;
}
tr.white-group {
  background: white;
}

For a working example, refer to this JSFiddle link.
