延迟使用jQuery更改innerHTML文本 [英] Delay changing innerHTML text using jQuery

问题描述

所以我有一个非常简单的按钮，基本上可以打开和关闭表单-我们将在我们的网站上使用此按钮，因为我们正在进行更新，并且希望在任何页面上都可以提供反馈.这是我到目前为止使用的jQuery:

So I've got a pretty simple button that basically toggles a form on and off - we'll be using this on our site since we're doing an update and would like feedback available on any page. Here's the jQuery I have so far:

<script>
// Toggle Button Text Change
$('#feedbackLink').hover(
    // Change HTML on mouseover
    function() {
        $(this).html('Send us a quick message!');
    },
    // Change back on mouseout
    function() {
        $(this).html('How can we improve this page?');
    }
);
// Toggle Button and Form
$('#feedbackLink').click(function() {
    // Hide feedback button
    $('#feedbackLink').toggle(500);
    // Display feedback form
    $('#feedbackForm').delay(501).toggle(250);
});
// Feedback Form
$('#cancel').click(function() {
    // Slides form from view when "CANCEL" is clicked
    $('#feedbackForm').toggle(500);
    // Fades original link back into view after a defined delay to allow for previous form to be hidden
    $('#feedbackLink').delay(501).toggle(75);
});
</script>

所以我的问题是，如何在.hover调用或.html交换中延迟或淡入淡出?

So my question is, how can I delay or fade in either the .hover call or the .html swap?

感谢您的帮助.

P.S. -我知道代码可以进一步优化，我只是想先使功能正常工作-然后我回过头来压缩我能做的事情.

P.S. - I know the code can be further optimized, I just like to get the functionality working first - then I go back and condense what I can.

推荐答案

您可以使用setTimeout():

var timeout;
$('#feedbackLink').hover(
    function() {
        clearTimeout(timeout);
        timeout = setTimeout(function() {
            $("#feedbackLink").html('Send us a quick message!');
        }, 2000); // change the HTML after 2 seconds
    },
    function() {
        clearTimeout(timeout);
        timeout = setTimeout(function() {
            $("#feedbackLink").html('How can we improve this page?');
        }, 2000); // change the HTML after 2 seconds
    }
);
