I am facing a challenge where I need to display a progress bar in my UI based on a percentage value stored in a JSON response object. Here is an example of the JSON object:
{
completionPercent: 42
}
The desired UI outcome should look like this:
┌──────────────────────────────────────────────────┐
|█████████████████████ |
└──────────────────────────────────────────────────┘
In my AngularJS project, I have bound the JSON object as the ng-model of an element. However, when trying to set the width of another element using completionPercent, I ran into an issue. The CSS width property requires a string formatted like '42%', not a number. So the initial approach did not work as expected:
<div id="progressBackground" ... >
<div id="progressBar"
ng-model="..."
ng-style="{ 'width': completionPercent }"
... ></div>
</div>
To overcome this hurdle, I ended up generating the complete style within the controller function like so:
ng-style="getStyleFromCompletionPercent()"
Although this solution works, it is not ideal for future modifications and scalability. I am exploring alternative methods to implicitly specify that the width should be in percentage. An approach similar to the following would be more efficient:
ng-style="{ 'width-percentage': completionPercent }"
