I have an ASP.NET ListBox containing a ‘No.1’ item and a linked label. My jQuery blur event fails to detect the selection correctly. How can I resolve this?
$("#dropdownBox").on("blur", function() {
var chosenValue = $(this).find("option:selected").text();
if (chosenValue === "No.1") {
$("#resultLabel").text(chosenValue);
}
});
I ran into a similar issue while testing dropdown controls in my project. I discovered that the blur event may trigger before the selection value is updated. For my use case, switching to the change event proved to be far more reliable. By doing so, I ensured that the correct option was selected since the event only fired after a new choice was made. It helped to eliminate the timing issue you seem to be facing. In essence, opting for the change event yielded consistent results when evaluating list item selections with JavaScript.
