Google Autocomplete Places API not triggering event on change via TAB

由 时间秒杀一切 提交于 2020-01-28 05:26:06
问题 Per the Google Autocomplete Places API documentation, the getPlace() call should return a Places object with all the location data, or, if that place doesn't exist (i.e. - the user ignored the suggestions), it should return a stub with just the name element of the Places object filled in. However, it only does this latter operation when the user hits ENTER, not if they TAB out of the field. I've tried looking at the change event, the keyup, keydown events. I've tried triggering a keydown

由 这一生的挚爱 提交于 2020-01-25 23:13:11
问题 I want to detect if the user pressed the browser's close button on a popup window in my application. By searching around I found this solution: $(window).bind('beforeunload', function(event) { $.ajax({url:"acquisition_cleanup.php", async:false}); var dataStr = 'id={id}'; $.ajax({ type: "POST", url: "acquisition_cleanup.php", data: dataStr, success: function() { window.close(); } }); }); It works well on my Ubuntu machine with Firefox 31. But unfortunatly it does not work on windows machine

问题 I have the following Onclick event onClick="document.body.style.background = 'url(galleries/g2.jpg)'" and when i attach it to <a onClick="document.body.style.background = 'url(galleries/g2.jpg)'"> blah</a> all works fine. but I want it as a body onclick event as follows <body class="g" onClick="document.body.style.background = 'url(galleries/g2.jpg)'"> and i get no dice.

Javascript Universal way to know added new element

由 时光总嘲笑我的痴心妄想 提交于 2020-01-24 21:37:25
问题 AddEventHandler in Javascript is for handling the events (like onclick) universally (i.e. on any element). Is there a way to fire an event (don't know which kind) when a new element (i.e input, div, select, etc.) is being added to the page (through Ajax, jQuery, etc.)?

If the reason is you want to add event handlers to new
