问题 I have a select field that is dynamically populated with an ajax call that simply returns all the HTML select options.

Trigger change() event when setting <select>'s value with val() function

由 别等时光非礼了梦想. 提交于 2019-11-26 21:57:32
What is the easiest and best way to trigger change event when setting the value of select element. I've expected that executing the following code $('select#some').val(10); or $('select#some').attr('value', 10); would result in triggering the change event, which i think is pretty logic thing to be done. Right? Well, it isn't the case. You need to triger change() event by doing this $('select#some').val(10).change(); or $('select#some').val(10).trigger('change'); but i'm looking for some solution which would trigger change event as soon as select's value is changed by some javascript code.

问题 I have 2 separate scripts that essentially do the same thing. I built them over time and just discovered I am using a couple different means to get to the same result. I want to standardize and use the best practices method in both cases. One way I test a change event is this: $('input[name="status"]').change(function() {}); Another way I am testing a change event is this: $("#email").bind("change", function(e) {}); Which way is best? What is the difference between the 2? Thanks for helping

jQuery change event being called twice

由 こ雲淡風輕ζ 提交于 2019-11-26 21:06:32
问题 I have a form with some input and select boxes, each has class="myClass" . I also have the following script: $(document).ready(function() { $(".myClass").change(function() { alert('bla'); }) }); I dont understand why after each change in select box or input box, this function is being called twice. What's wrong here? Appreciate your help! 回答1: All I can think of is that you used the same class on the form itself. if so, remove the myClass style from your form tag. Corrected : http://jsfiddle

问题 I am working on this html5 file uploader plugin but it has a bug on Google Chrome which I can't understand and fix it. It works fine on Firefox. jsfiddle link The problem is that you cannot upload the same file twice from your desktop. When you first click, select, and hit OK to upload a file from your desktop, it should alert a message, for instance '.button-1' - depends on which upload button you click. Then if you try to upload the same file again, this line of code won't be executed

问题 The "onchange" event is triggered only when the USER enters some value. Why isn't possible to fire the event when I change the value automatically via Javascript ? Is there an alternative ?

问题 Does anyone know any workarounds for this? I'm trying to use a select element for navigation. It looks something like this; <select onchange="window.location=(this.options[this.selectedIndex].value)"> It works on all desktop browsers and it also works on my WP7 phone. It doesn't work on my iPhone (iOS 5.0). 回答1: iOS tends to not fire change events when you change the value of their inputs. I've documented this in more depth at the Device-Bugs tracker. The workaround is to bind to the blur
