javascript file input onchange not working [ios safari only]

寵の児 提交于 2019-12-04 06:17:37
The code below works everywhere except on safri mobile. Apparently the onchange is never triggered. // create a hidden file input element var input = document.createElement("input"); input.type = "file"; // when the input content changes, do something input.onchange = function(event) { // upload files } // Trigger file browser input.click(); I have found similar examples however they all refer to scenarios where there is even a form of some other visible representation of the file input and they all involve form-clearing workarounds. That wouldn't work here. This code is being called upon

Attaching onchange function event to variable

我们两清 提交于 2019-12-04 06:08:13
I recently got into closures and anonymous functions, and I'm wondering if my code is the right way to do it (it works!): newInput.onchange = function(x){ return function(){ PassFileName(x); } }(counter); so this is in a loop that "saves" the current 'counter' value (1,2,3...). If I didn't have the return function, then 'counter' will always be the last value of 'counter'. Am I approaching this correctly with that code? or is there a better way to "capture" the current counter and attach it to an onchange event? thank you! Yes, you're approaching it correctly, but for maximum compatibility

Delphi TListBox OnClick / OnChange?

試著忘記壹切 提交于 2019-12-04 05:04:15
Is there a trick to getting "OnChange" type of functionality with a TListBox? I can subclass the component and add a property, etc then only carry out OnClick code if the Index changes... I can also hack it with a form level variable to store the current index but just wondering if I'm overlooking the obvious before I go one way or the other. There seems to be no way other than implementing this by yourself. What you need is to remember the currently selected item and whenever the ItemIndex property is changed from code or whenever the control receives the LBN_SELCHANGE notification (which

I wrote a code that when the button is clicked, the 'Hello' text is inputted into the the textbox. But the onchange event of the textbox is not working well.

Javascript detect a selection of browser AutoComplete value

老子叫甜甜 提交于 2019-12-04 03:33:49
I have a text field with an onkeyup event. But this event is not fired when I select a browser autoComplete value. I have added an onclick event, but it doesn't work. I have tested many solutions posted on stackoverflow for catching the browse autocoComplete selection, but nothing has resolved this problem. Try this simple example to see the issue (reproduced on Firefox 3.6, Chrome 10.0 and IE8): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <title>Test</title> <script type="text/javascript" src="http:/

问题 I have a textarea. After writing some misspelled text and using rightclick -> correction the word gets replaced with a correctly spelled word. Now, my problem here is that i need to exectue some javascript code when the correction gets done. How can i catch the firefox spellcheck correction event?
