我在tuts之后创建了一个简单的插件,并修改它以做我想要的。 它基本上创建了一个“工具提示”,我试图在一段时间内保持可见状态,但也允许用户点击块以便通知而不是工具提示。到目前为止我所拥有的是在下面,但是当它没有自动隐藏时......然而,点击关闭工作。谁能发现我做错了什么/改进?
$.fn.betterTooltip = function(options){
/* Setup the options for the tooltip that can be
accessed from outside the plugin */
var defaults = {
speed: 200,
delay: 300,
hideAfter:5000
};
var options = $.extend(defaults, options);
/* Create a function that builds the tooltip
markup. Then, prepend the tooltip to the body */
getTip = function() {
var tTip =
"<div class='tip'>" +
"<div class='tipMid'>" +
"</div>" +
"<div class='tipBtm'></div>" +
"</div>";
return tTip;
}
$("body").prepend(getTip());
/* Give each item with the class associated with
the plugin the ability to call the tooltip */
$(this).each(function(){
var $this = $(this);
var tip = $('.tip');
var tipInner = $('.tip .tipMid');
var tTitle = (this.title);
this.title = "";
var offset = $(this).offset();
var tLeft = offset.left;
var tTop = offset.top;
var tWidth = $this.width();
var tHeight = $this.height();
/* Delay the fade-in animation of the tooltip */
setTimer = function() {
$this.showTipTimer = setInterval("showTip()", defaults.delay);
}
hideTip=function(){
stopTimer();
tip.hide();
}
stopTimer = function() {
clearInterval($this.showTipTimer);
clearInterval( $this.hideTimer);
}
/* Position the tooltip relative to the class
associated with the tooltip */
setTip = function(top, left){
var topOffset = tip.height()-30;
var xTip = (left+60)+"px";
var yTip = (top-topOffset)+"px";
tip.css({
'top' : yTip,
'left' : xTip
});
}
/* This function stops the timer and creates the
fade-in animation */
showTip = function(){
stopTimer();
tip.animate({
"top": "+=20px",
"opacity": "toggle"
}, defaults.speed);
}
$(this).ready(function() {
tipInner.html(tTitle+'<br />(Click to dismiss)');
setTip(tTop, tLeft);
setTimer();
hideTimer=function(){
$this.hideTimer=setInterval("hideTip()",defaults.hideAfter);
}
hideTimer();
});
$(tip).click(function() {
hideTip();
});
});
};

我认为您需要setTimeout
和clearTimeout
而不是...Interval
版本。前者一次发起回调,而后者反复发作。
一些提示:
setTimeout
或setInterval
以使代码运行 - 使用函数指针。我发现它不容易出错,并且范围从来都不是问题。mouseleave
事件的提示(来自提示所针对的项目或提示本身),并在mouseover
或mouseenter
上显示。这比让javascript一直运行更有效。
