问题描述

我正在尝试从元素取消绑定mouseup事件.我已经尝试了以下方法，但是都无法正常工作.

I am trying to unbind the mouseup event from an element. I have tried the following but none are working.

$('#myElm').unbind('mouseup');
$('#myElm').unbind('onmouseup');
$('#myElm').unbind('click');

如何取消绑定使用$('#myElm').mouseup(function({...});分配的事件???

How do you unbind an event assigned using $('#myElm').mouseup(function({...}); ???

修改:添加完整代码

cacheBgArea.mouseup(function(){
      var $cursorInElm = $(cacheBgArea.selectedText().obj);
      var selectFontSize = parseInt($cursorInElm.css('fontSize')), selectFontFace = $cursorInElm.css('fontFamily');
      $fontSizeSlider.slider('value', selectFontSize);

      $chooseFontFace.find('option').each(function(){
         var $this = $(this);
         if ($this.val() == selectFontFace) {
            $this.attr('selected', true);
            return false;
         }
      });
      log('font weight: ' + $cursorInElm.css('fontWeight'));
      if ($cursorInElm.css('fontWeight') == 'bold' || $cursorInElm.css('fontWeight') == 401) {
         $boldCheckbox.attr('checked', true).change();
      } else {
         $boldCheckbox.attr('checked', false).change();
      }

      var objText = cacheBgArea.selectedText();
      if (objText.obj.nodeName == 'a' || objText.obj.nodeName == 'A') {
         $cursorInElm = $(objText.obj)
         var elmsHref = $cursorInElm.attr('href');
         if (elmsHref && elmsHref != '#') {
            $enterOwnLink.val(elmsHref).show();
            $switchToPage.show();
            $chooseLinkPage.hide();
            $chooseLinkTitle.html('Enter a Web Address');
         } else if ($cursorInElm.attr('linkPageId')) {
            $chooseLinkPage.find('option').each(function(){
               var $this = $(this);
               if ($this.val() == $cursorInElm.attr('linkPageId')) {
                  $this.attr('selected', true);
                  return false;
               }
            });
            $enterOwnLink.hide();
            $switchToPage.hide();
            $chooseLinkPage.show();
            $chooseLinkTitle.html('Choose a Page');
         }
      } else {
         $('#noneLink').attr('selected', true);
         $enterOwnLink.hide();
         $switchToPage.hide();
         $chooseLinkPage.show();
         $chooseLinkTitle.html('Choose a Page');
      }
   });

我已经验证过cacheBgArea确实已定义.是的，事件是在调用取消绑定之前绑定的.这是解除绑定. (日志只是我console.log()的简写).

I have verified that cacheBgArea in indeed defined. Yes, the event is bound before the unbind is called. This is the unbind. (log is just my shorthand for console.log();)

log('cacheBgArea.length: ' + cacheBgArea.length);
cacheBgArea.unbind('mouseup');//TODO: fix this, not unbinding...

推荐答案

这应该有效:

$('#myElm').unbind('mouseup');

您可以发布完整的绑定代码吗?另外，您确定在 .mouseup() 运行后运行吗?

Can you post your complete bind code? Also, are you sure this is running after the .mouseup() ran?

.mouseup(func) 是 .bind('mouseup', func) ，因此匹配取消绑定为 (请注意，这会取消绑定 all处理程序的所有mouseup处理程序，而不仅仅是匿名函数，如果要删除特定的处理程序，则需要命名函数).

.mouseup(func) is a shortcut for .bind('mouseup', func) so the match unbind is .unbind('mouseup') (note this unbinds all of the mouseup handlers, not just the anonymous function, you'll need a named function if you want to remove a specific handler).
