jQuery 可选事件
我有一个 jQuery 插件,可以将元素拖放到不同的容器中,我想附加一些事件,例如当元素位于容器上方时。这些事件过去运行得很好,但后来就停止了。由于某种原因,可选择的特定事件不会被触发,但是当我绑定一个点击时,它会起作用。
示例:
//these are not working
$('#sortable2').bind("sortover", function(event, ui) {
alert("here");
});
$('#sortable2').bind('sortreceive', function() {
alert('User clicked on "sortable2."');
});
$('.droptrue').bind("sortout", function(event, ui) {
$(this).css("background", "transparent");
});
相关代码为:
var selectedClass = 'ui-state-highlight',
clickDelay = 300, // click time (milliseconds)
lastClick, diffClick; // timestamps
$("ul.droptrue li")
// Script to deferentiate a click from a mousedown for drag event
.bind('mousedown mouseup', function(e){
if (e.type=="mousedown") {
lastClick = e.timeStamp; // get mousedown time
} else {
diffClick = e.timeStamp - lastClick;
if ( diffClick < clickDelay ) {
// add selected class to group draggable objects
$(this).toggleClass(selectedClass);
}
}
})
.draggable({
revertDuration: 10, // grouped items animate separately, so leave this number low
containment: '.multiSelect',
start: function(e, ui) {
ui.helper.addClass(selectedClass);
},
stop: function(e, ui) {
// reset group positions
$('.' + selectedClass).css({ top:0, left:0 });
},
drag: function(e, ui) {
// set selected group position to main dragged object
// this works because the position is relative to the starting position
$('.' + selectedClass).css({
top : ui.position.top,
left: ui.position.left
});
}
});
$("ul.droptrue")
.sortable()
.droppable({
drop: function(e, ui) {
$('.' + selectedClass)
.appendTo($(this))
.add(ui.draggable) // ui.draggable is appended by the script, so add it after
.removeClass(selectedClass)
.css({ top:0, left:0 });
}
});
$('#total').text(autoCompleteSourceArray.length);
$('#filter-count').text(autoCompleteSourceArray.length);
//Adding Filtering functionality for the lists
$("#filter").keyup(function () {
var filter = $(this).val(), count = 0;
$("ul.droptrue:first li").each(function () {
if ($(this).text().search(new RegExp(filter, "i")) < 0) {
$(this).addClass("hidden");
} else {
$(this).removeClass("hidden");
count++;
}
});
$("#filter-count").text(count);
});
// bind events in order to show or hide the message in the drop zones
$('ul[id^="sortable"]').live("sortover", function(event, ui) {
$(this).css("background", "#f7f6d7");
});
$('ul[id^="sortable"]').live("sortout", function(event, ui) {
$(this).css("background", "transparent");
});
非常感谢
I have a jQuery plugin that drags and drops elements into different containers, I want to attach some events, for example when an element is over a container. These events used to work perfectly but then they stopped working. for Some reason the Selectable specific events are not fired, but when i bind a click for example it works.
Example:
//these are not working
$('#sortable2').bind("sortover", function(event, ui) {
alert("here");
});
$('#sortable2').bind('sortreceive', function() {
alert('User clicked on "sortable2."');
});
$('.droptrue').bind("sortout", function(event, ui) {
$(this).css("background", "transparent");
});
The related code is:
var selectedClass = 'ui-state-highlight',
clickDelay = 300, // click time (milliseconds)
lastClick, diffClick; // timestamps
$("ul.droptrue li")
// Script to deferentiate a click from a mousedown for drag event
.bind('mousedown mouseup', function(e){
if (e.type=="mousedown") {
lastClick = e.timeStamp; // get mousedown time
} else {
diffClick = e.timeStamp - lastClick;
if ( diffClick < clickDelay ) {
// add selected class to group draggable objects
$(this).toggleClass(selectedClass);
}
}
})
.draggable({
revertDuration: 10, // grouped items animate separately, so leave this number low
containment: '.multiSelect',
start: function(e, ui) {
ui.helper.addClass(selectedClass);
},
stop: function(e, ui) {
// reset group positions
$('.' + selectedClass).css({ top:0, left:0 });
},
drag: function(e, ui) {
// set selected group position to main dragged object
// this works because the position is relative to the starting position
$('.' + selectedClass).css({
top : ui.position.top,
left: ui.position.left
});
}
});
$("ul.droptrue")
.sortable()
.droppable({
drop: function(e, ui) {
$('.' + selectedClass)
.appendTo($(this))
.add(ui.draggable) // ui.draggable is appended by the script, so add it after
.removeClass(selectedClass)
.css({ top:0, left:0 });
}
});
$('#total').text(autoCompleteSourceArray.length);
$('#filter-count').text(autoCompleteSourceArray.length);
//Adding Filtering functionality for the lists
$("#filter").keyup(function () {
var filter = $(this).val(), count = 0;
$("ul.droptrue:first li").each(function () {
if ($(this).text().search(new RegExp(filter, "i")) < 0) {
$(this).addClass("hidden");
} else {
$(this).removeClass("hidden");
count++;
}
});
$("#filter-count").text(count);
});
// bind events in order to show or hide the message in the drop zones
$('ul[id^="sortable"]').live("sortover", function(event, ui) {
$(this).css("background", "#f7f6d7");
});
$('ul[id^="sortable"]').live("sortout", function(event, ui) {
$(this).css("background", "transparent");
});
Thanks a lot

如果您最近更新到 jQuery 1.7+,您应该注意到
live()
方法已被弃用。If you have recently updated to jQuery 1.7+ you should notice that the
live()
method is deprecated.
