Alternative to “onChange” event with Semantic UI dropdown?





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

This is a dumb question but I've been all over the Semantic UI site, along with searching here and I haven't found a solution.



The gist is: I have been using the code below with a Semantic dropdown list. It works fine – except that I have a table component through which the user can also make a selection (which triggers a function) – and when they do, I update the Semantic dropdown to reflect the current selection . . . and then the onChange event fires – so a function is running twice when it doesn't need to.



I tried using onSelect but that is apparently not a valid event for a dropdown. I could do some stupid hack to work around this but I'd rather just use a different event. Is there one?





$(function () {
$('#productStates').dropdown({
allowAdditions: true,
allowReselection: true,
placeholder: "Select State",
onChange: function (value, text) {
if (projectData == undefined) return;
loadStateByID(value)
}
})
});

Ok - solved this. Wish the Semantic docs were clearer on event handling.



I was trying to prevent a "loading" function from getting called twice when a user clicked on a table cell and the dropdown was updated to reflect the current selection. I update the dropdown using:



$('#productStates').dropdown('set selected', activeStateID);


The onChange event handler captured all changes and so the "load" event would fire twice. Using action, the event only fires on a user action, not on setting the dropdown state through code.



$('#productStates').dropdown({
allowAdditions: true,
allowReselection: true,
placeholder: "Select State",
action: function (value, text) {
if (projectData == undefined) return;
$(this).dropdown('set selected', value);
loadStateByID(text)
}
})
