How to differentiate between click and drag/drop event?

I have a problem with element which is both draggable and also has a click event.

$('.drag').mousedown(function() {
    //...
});

$('.class').click(function() {
开发者_JS百科    //...
)};

<div class="drag class"></div>

When I drag and drop the element, the click event gets fired, too. How to prevent that?

Also you could probably do something with the mousemove and mousedown events together to disable the click event:

var dragging = 0;

$('.drag').mousedown(function() {
    $(document).mousemove(function(){
       dragging = 1;
    });
});

$(document).mouseup(function(){
    dragging = 0;
    $(document).unbind('mousemove');
});

$('.class').click(function() {
    if (dragging == 0){
       // default behaviour goes here
    }
    else return false;
)};

You should be able to do that by stopping the propagation on the mousedown event.

$('.drag').mousedown(function(event){
  event.stopPropagation();
});  

You may have to make sure that this event is attached before the click event though.

In my case selected answer didn't worked. So here is my solution which worked properly(may be useful for someone):

    var dragging = 0;
    $(document).mousedown(function() {
        dragging = 0;
        $(document).mousemove(function(){
           dragging = 1;
        });
    });

    $('.class').click(function(e) {
        e.preventDefault();
        if (dragging == 0){
            alert('it was click');
        }
        else{
            alert('it was a drag');
        }
    });

I noticed that if the drag event is registered prior to click event then the problem described will not happen. Here is an example code:

This code create the mentioned problem:

        var that = this;
        var btnId = "button_" + this.getId();
        var minView = $("<div>", {"id":btnId, style:"position:absolute; top:"
            + this.options.style.top + ";left:" + this.options.style.left + ";border:1px solid gray;padding:2px"});
        minView.html(this.getMinimizedTitle());

        minView.click(function expendWidget(event) {
            $("#" + btnId).remove();
            that.element.css({"left":that.options.style.left, "right":that.options.style.right});
            that.element.show();
        });

        minView.draggable();
        minView.on("drag", this.handleDrag.bind(this));

        this.element.parent().append(minView);

this code does not create the problem:

        var that = this;
        var btnId = "button_" + this.getId();
        var minView = $("<div>", {"id":btnId, style:"position:absolute; top:"
            + this.options.style.top + ";left:" + this.options.style.left + ";border:1px solid gray;padding:2px"});
        minView.html(this.getMinimizedTitle());

        minView.draggable();
        minView.on("drag", this.handleDrag.bind(this));

        minView.click(function expendWidget(event) {
            $("#" + btnId).remove();
            that.element.css({"left":that.options.style.left, "right":that.options.style.right});
            that.element.show();
        });
        this.element.parent().append(minView);

It's ok, but you should alway remember, that user can move mouse slightly during the click and don't notice that. So he'd think hi clicked and you – that he dragged
