我有一个系统允许用户标记图像,他们点击图像和框出现让他们输入他们的朋友的名字,然后从自动完成时,他们要么点击保存按钮或者点击进入输入密钥为.on()触发两次
$("#imgtag img").click(function(e){ // make sure the image is clicked
var imgtag = $(this).parent(); // get the div to append the tagging entry
mouseX = e.pageX - $(imgtag).offset().left; // x and y axis
mouseY = e.pageY - $(imgtag).offset().top;
mouseY = (mouseY-60);
mouseX = (mouseX-90);
$('#tagit').remove(); // remove any tagit div first
$(imgtag).append('<div id="tagit"><div class="box"></div><div class="name"><input type="text" name="name" id="tagName" /><input type="button" name="btnsave" value="Save" id="btnsave" /><input type="button" name="btncancel" value="Cancel" id="btncancel" /></div></div>');
$('#tagit').css({top:mouseY,left:mouseX});
$("#tagName").autocomplete({
source: data,
select: function(event, ui) {
$("#tagName").val(ui.item.label);
return false;
}
});
$('#tagName').focus();
$('#tagName').keyup(function(event){ // this fires twice
if(event.keyCode == 13){
$('#btnsave').trigger('click');
}
});
});
这是如果我移动$('#tagName').keyup(function(event){ if(event.keyCode == 13){}}
出#imgtag img
范围不会在所有的工作中节省了数据
$(document).on('click', '#btnsave', function() {
name = $('#tagName').val();
counter++;
$('#taglist ol').append('<li rel="'+counter+'"><a>'+name+'</a> (<a class="remove">Remove</a>)</li>');
$('#imgtag').append('<div class="tagview" id="view_'+counter+'"></div>');
$('#view_' + counter).css({top:mouseY,left:mouseX});
$('#tagit').fadeOut();
// add backend code here, use mouseX and mouseY for the axis and counter.
});
的代码,但它现在是就像点击twi的#btnsave
按钮ce,这应该是不可能的,因为当按钮被点击一次时,围绕的div被移除。
这实际上是完美的,当它实际上点击它只是触发两次的按钮,而不是使用输入按钮。
任何想法,为什么这会在输入时触发两次?
UPDATE我现在已经搬到了点击了#imgtag点击功能 - 感谢的是,也略有不同回车键码,但仍然发射
$("#imgtag img").click(function(e){ // make sure the image is clicked
var imgtag = $(this).parent(); // get the div to append the tagging entry
mouseX = e.pageX - $(imgtag).offset().left; // x and y axis
mouseY = e.pageY - $(imgtag).offset().top;
mouseY = (mouseY-60);
mouseX = (mouseX-130);
$('#tagit').remove(); // remove any tagit div first
$(imgtag).append('<div id="tagit"><div class="box"></div><div class="name"><input type="text" name="name" id="tagName" /><input type="button" name="btnsave" value="Save" id="btnsave" /><input type="button" name="btncancel" value="Cancel" id="btncancel" /></div></div>');
$('#tagit').css({top:mouseY,left:mouseX});
$("#tagName").autocomplete({
source: "/ajax/fbFriendsAutoC.php",
select: function(event, ui) {
$("#tagName").val(ui.item.name); // on select place friend name to input
$("#uid").val(ui.item.uid); // temp place for uid
return false;
}
}).data("ui-autocomplete")._renderItem = function(ul, item) { // how our list will looks
return $("<li></li>")
.append("<a><img src='" + item.pic_square + "' height=32 /><div class='fbName'>" + item.name + "</div></a>")
.data("item.autocomplete", item) .appendTo(ul);
};
$('#tagName').focus();
});
$(document).keyup(function(e) {
if (e.keyCode == 13) { $('#btnsave').trigger('click'); } // enter
if (e.keyCode == 27) { $('#tagit').fadeOut(); } // esc
});
$(document).on('click', '#btnsave', function() {
uid = $('#uid').val();
var hdnValue = $('#tags').val();
$('#tags').val(hdnValue + uid + ','+ mouseX + ',' + mouseY + ',');
name = $('#tagName').val();
counter++;
$('#taglist ul').append('<li rel="'+counter+'"><a>'+name+'</a> (<a class="remove">Remove</a>)</li>');
$('#imgtag').append('<div class="tagview" id="view_'+counter+'"></div>');
$('#view_' + counter).css({top:mouseY,left:mouseX});
$('#tagit').fadeOut();
});
当你'返回false会发生什么;'在最后点击事件监听器? –
