Change the selected value of a drop-down list with jQuery

📝🤔 Change the selected value of a drop-down list with jQuery! 😄

Are you struggling to set the selected value of a drop-down list using jQuery? 🤷‍♀️ No worries, I've got your back! Here's a guide that will help you overcome this challenge and make your life easier. 💪

So, you have a drop-down list with known values, and you want to set a particular value using jQuery. To accomplish this, you can use the following code in regular JavaScript:

ddl = document.getElementById("ID of element goes here");
ddl.value = 2; // The value you want to set it to.

But, since you are using a CSS class as your selector (thanks to the quirky ASP.NET client ids 😒), you need to do it with jQuery. Let's explore some options you might have considered and their drawbacks:

$("._statusDDL").val(2); // Doesn't find 2 as a value.
$("._statusDDL").children("option").val(2); // Also failed.

These attempts might have left you scratching your head, wondering what went wrong. But fear not, my friend! The solution is simpler than you think. 😊

To change the selected value of a drop-down list with jQuery, you can use the following piece of code:

$("._statusDDL").val(2);

Yes, that's right! Just one line of code does the trick. 🎉

Now, here comes the tricky part. In some cases, you might encounter an error message like "Could not set the selected property. Invalid Index." 🙄 This issue typically arises when running the code without any pauses, especially in Internet Explorer 6. It could be a bug with jQuery or the browser itself.

But worry not, my friend! I have a workaround for you. Simply add an alert just above the code, like this:

alert("Pause for a moment. I'm about to set the selected value.");
$("._statusDDL").val(2);

This will give the browser a slight pause and allow the code to run smoothly. Once everything is working as expected, you can safely remove the alert. 😉

And there you have it! Now you know how to change the selected value of a drop-down list using jQuery. You can impress your friends and colleagues with your newfound knowledge. 🤓
