我的JS:
$("#modalADDpp").on('shown',function(e){
$(this).find('input[type=text]').filter(':first').focus();
var count = 0;
alert(count);
$('#pp_tab a').click(function () {
$(this).tab('show');
})
$("#TenPP").typing({ // jquery for check when finish typing
start: function(event ,$elem) {
$(".add-on").remove();
return false;
},
stop: function (event, $elem) {
count ++;
alert(count);
if(count == 1 )
{
Ajax_Check_Name($elem);// Check name same with database by ajax
}
return false;
},
delay: 500
});
$("#modalADDpp").on('hidden',function(e){
$(this).closest('form').find("input[type=text], textarea").val("");
$(".add-on").remove();
});
});
我的模态中显示$ count = 0。第一次,它工作正常。但是当隐藏模态并重新打开时,$ count not = 0,$ count now = 2 =>我的功能将调用两次,如果再次关闭,则加上3次,4次,5次。
我用
if(count == 1)
因为我希望它只运行一次。所以它工作正常,但我不知道问题出在哪里。需要帮助!!!
输入代码.js
(function ($) {
//--------------------
// jQuery extension
//--------------------
$.fn.typing = function (options) {
return this.each(function (i, elem) {
listenToTyping(elem, options);
});
};
//-------------------
// actual function
//-------------------
function listenToTyping(elem, options) {
// override default settings
var settings = $.extend({
start: null,
stop: null,
delay: 400
}, options);
// create other function-scope variables
var $elem = $(elem),
typing = false,
delayedCallback;
// start typing
function startTyping(event) {
if (!typing) {
// set flag and run callback
typing = true;
if (settings.start) {
settings.start(event, $elem);
}
}
}
// stop typing
function stopTyping(event, delay) {
if (typing) {
// discard previous delayed callback and create new one
clearTimeout(delayedCallback);
delayedCallback = setTimeout(function () {
// set flag and run callback
typing = false;
if (settings.stop) {
settings.stop(event, $elem);
}
}, delay >= 0 ? delay : settings.delay);
}
}
// listen to regular keypresses
$elem.keypress(startTyping);
// listen to backspace and delete presses
$elem.keydown(function (event) {
if (event.keyCode === 8 || event.keyCode === 46) {
startTyping(event);
}
});
// listen to keyups
//$elem.keyup(stopTyping);
// listen to blurs
$elem.blur(function (event) {
stopTyping(event, 0);
});
}
})(jQuery);
答案 0 :(得分:0)
尝试将计数重置为0 ...隐藏或停止功能......
if(count == 1 )
{
Ajax_Check_Name($elem);// Check name same with database by ajax
count = 0;
}
或
$("#modalADDpp").on('hidden',function(e){
$(this).closest('form').find("input[type=text], textarea").val("");
$(".add-on").remove();
count = 0;
});
