我在我的网站上使用了一些文本框(输入类型=文本),并且我有一个 div,它是隐藏的(显示:无)。
现在我希望用户在其中一个文本框中输入一些文本,就在那一刻,当用户停止添加文本时,div 应该出现几秒钟并隐藏。 div 还应该等待,直到用户停止将鼠标悬停在 div 上。我真的很努力,但没能正确完成。
这是一个 JSFIDDLE 示例来说明我的意思:
var InfoBoxHovered = false;
$(".TextBox1").on("input", function() {
$(".InfoBox").fadeIn();
setTimeout(function () {
$(".InfoBox").fadeOut();
}, 3000);
});
$(".TextBox2").on("input", function() {
$(".InfoBox").fadeIn();
if (!InfoBoxHovered){
setTimeout(function () {
$(".InfoBox").fadeOut();
}, 3000);
}
});
$(".InfoBox").mouseenter(function(){
InfoBoxHovered = true;
})
$(".InfoBox").mouseleave(function(){
InfoBoxHovered = false;
})
// - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - //
//The INFOBOX-DIV should APPEAR, when the user enters some text
//The INFOBOX-DIV should DISAPPEAR, 3 SECONDS AFTER THE USER STOPPED ENTERING TEXT
//The Infobox-Div should not disappear after 3 seconds and appear again - it should stay until the user finished entering text and then wait 3 seconds before it fades out
//The InfoBox-div should be visible, as long as the user hovers the div and should then fade out, if the 3 seconds are over
.Main{
background-color: lightgrey; min-width: 100%; min-height: 200px; text-align: center;
}
.Header{
font-family: Arial; color: red; font-size: 18px; font-weight: bold;
}
.InfoBox{
position: fixed; left:0; right:0;background: rgba(0,0,0,.75); z-index: 20; bottom: 20px;
margin: 0 auto; width: 500px; height: 80px; border-radius: 4px; text-align: center;
color: white; padding: 15px; font-family: Arial; display: none;
}
<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>
<div class="Main">
<br/>
<span class="Header">Input-Fields</span>
<br/><br/>
<input type="text" name="title1" placeholder="Enter Some Text" class="TextBox TextBox1"/>
<input type="text" name="titlew" placeholder="Enter Some Text" class="TextBox TextBox2"/>
</div>
<div class="InfoBox">
Information
</div>
我尽了最大努力使用不同的功能,如“delay”或“setTimeout”,甚至用“SetInterval”每隔几秒检查一次......但没有任何效果。我尝试在 JSFiddle 的 JavaScript-Field 中解释更多细节。
提前致谢。
最佳答案
您所要做的就是将 setTimeout
存储在变量中,然后在需要时清除该超时:
用 hover
替换了 mouseenter
,但无论哪种方式都可以工作。
注意
.InfoBox
元素最初是不可见的,因此当它出现在鼠标指针下方时,在鼠标指针移动之前它不会悬停。
// declare timer variable which holds the timeout:
var timer;
$(".TextBox1").on("input", function() {
$(".InfoBox").fadeIn();
// clear the timer if it's already set:
clearTimeout(timer);
timer = setTimeout(function () {
$(".InfoBox").fadeOut();
}, 3000);
});
$(".TextBox2").on("input", function() {
$(".InfoBox").fadeIn();
// clear the timer if it's already set:
clearTimeout(timer);
timer = setTimeout(function () {
$(".InfoBox").fadeOut();
}, 3000);
});
$(".InfoBox").hover(function(){
// clear the timer on hover, so that the box won't disapear:
clearTimeout(timer);
}, function(){
// set the timer again when mouse is outside of the box:
timer = setTimeout(function () {
$(".InfoBox").fadeOut();
}, 3000);
});
