The ng-model is being set to the default value, however the select element fails to display the text and instead appears blank

Having trouble displaying a default option in a select tag after retrieving a list of options from the server. The model is being set correctly, but the select shows up blank, and I can't figure out why!

I've attempted various solutions from Stack Overflow, such as here, here, and here.

Here's a snippet of the code:

<select ng-options="option as option.Name for option in options track by option.ID" ng-model="selected">

In the controller:

DataService.getOptionsFromServer().then(function (result) {
    $scope.options = result.data;
    $scope.selected = $scope.options[0];
}, function (err) {
    console.error(err);
});

Even though the console logs show that the selected option is set correctly, the select remains empty. Any ideas?

Update1: It appears there may be compatibility issues between Angular and jQuery Mobile (which I didn't add to the project). Any insights on this?

Update2: Removing jquery.mobile.min.js resolves the issue, but unfortunately, it's needed for the project.

Update3: The problem lies in the fact that jQuery Mobile generates a span to display the selected value. This prevents proper binding as the select is bound, not the span. Having trouble finding a solution as the span is generated at runtime by JQM.

Updated4: Issue resolved! See solution below for future reference.

Answer №1

The issue lies in JQM not directly displaying the selected value, but instead retrieving the value, placing it in a span at runtime, and then hiding the select altogether. It took me over 12 hours to figure this out the hard way!

In order for JQM to refresh and update the selected value displayed in the span, you need to use the following code:

jQuery("#SelectId").selectmenu("refresh", true);

It's important to note that if you're using Angular, it's advisable to use "jQuery" instead of "$" to prevent conflicts between Angular and jQuery.

Don't underestimate the significance of that one line of code - it took more than a full workday to discover its importance. Hopefully, this information proves helpful!

Reference: here.

Additionally, if you plan on using the select feature multiple times, consider creating an Angular directive for convenience.

Answer №2

It appears that there may be an issue with receiving data from the server. Could you please verify this?
