jqGrid Cell Editing - Double Click to Edit?

阅读更多关于 jqGrid Cell Editing - Double Click to Edit?

问题 By default, if a jqGrid cell is editable, single click on that cell changes it to edit mode. Is there any way I can make it edit on a double click instead? It would make it easier to do row-level operations such as deleting, as all the columns in my grid are editable. 回答1: Yes, you can use the ondblClickRow event to capture a double-click. Here is a simple example to get you started: ondblClickRow: function(){ var row_id = $("#grid").getGridParam('selrow'); jQuery('#grid').editRow(row_id,

Click event called twice on touchend in iPad

阅读更多关于 Click event called twice on touchend in iPad

I am using jquery animate for the slide. I have an arrow at the end of the slide and given the click event on that arrow. The working of it is to move one item inside the silde on click and move the entire silde on mousedown. This is working fine in desktop but in iPad two items are coming inside the slide at a time on click. I am not understanding why the click event is called twice in iPad. The sample code for the click is : $('#next_item').bind('mousedown touchstart MozTouchDown',function(e) { $('.slide').animate({left:left},6000); }); $('#next_item').bind('mouseup touchend MozTouchRelease'

Jquery click event propagation

问题 I have a table with click events bound to its rows ( <tr> ). There are <a> elements inside those rows with their own click events assigned. Problem is, when i click on the <a> element, it also fires the click event from the parent <tr> . I don't want this behavior; I just want to fire the <a> click event. Code: // Event row TR $("tr:not(:first)").click(function() { $(".window, .backFundo, .close").remove(); var position = $(this).offset().top; position = position < 0 ? 20 : position; $("body"

jQuery, checkboxes and .is(“:checked”)

阅读更多关于 jQuery, checkboxes and .is(“:checked”)

When I bind a function to a checkbox element like: $("#myCheckbox").click( function() { alert($(this).is(":checked")); }); The checkbox changes its checked attribute before the event is triggered, this is the normal behavior, and gives an inverse result. However, when I do: $("#myCheckbox").click(); The checkbox changes it checked attribute after the event is triggered. My question is, is there a way to trigger the click event from jQuery like a normal click would do (first scenario)? PS: I've already tried with trigger('click') ; $('#myCheckbox').change(function () { if ($(this).prop("checked
