live 绑定事件会触发多次

当页面不刷新时, 多次操作某事件,  live绑定的事件会触发多次, 用bind可避免:

$("#bt_send").live("click",function(){        
        var mobileSelectedUsers='';
        $("#se_mobile_users").find('.ui-widget-content').each(function() {
            if(IsInteger(this.value)){
                mobileSelectedUsers+=this.value+',';
            }
        });
        
        $("input[name='mobile_user_ids']").attr("value", mobileSelectedUsers);
        //alert(mobileSelectedUsers);
        addedit_form_post.submit();
        return false;
    });

应改成:

$("#bt_send").bind("click",function(){        
        var mobileSelectedUsers='';
        $("#se_mobile_users").find('.ui-widget-content').each(function() {
            if(IsInteger(this.value)){
                mobileSelectedUsers+=this.value+',';
            }
        });
        
        $("input[name='mobile_user_ids']").attr("value", mobileSelectedUsers);
        //alert(mobileSelectedUsers);
        addedit_form_post.submit();
        return false;
    });
