是否有可能使锚标记的标题属性在鼠标悬停时立即出现，而不是在几秒钟后出现。 JavaScript/jQuery 和 CSS 中的任何解决方案都很好。
title可以使用其他技术来代替title
属性。其中一些在其他答案中已经提到过。请注意，简单的“CSS 工具提示”可以在纯 CSS 中相当简单和灵活地实现。使用这些技术时，要显示的数据通常是not 在
title属性中，因为它的处理取决于浏览器，因此存在让您的特殊工具提示显示和 浏览器的 实现的风险
title。尽管可以防止后者，但在启用脚本时，使用对任何内容都没有默认效果的属性会更简单，例如
data-title=...或
data-tooltip=...。
// textFrom : String, the attribute from which the text
// should come,
// delta : String or Number, the distance from the cursor at
// which the tooltip should appear
function instantTooltips(textFrom, delta) {
// if delta exists, and can be parsed to a number, we use it,
// otherwise we use the default of 5:
delta = parseFloat(delta) ? parseFloat(delta) : 5;
// function to handle repositioning of the created tooltip:
function reposition(e) {
// get the tooltip element:
var tooltip = this.nextSibling;
// setting the position according to the position of the
// pointer:
tooltip.style.top = (e.pageY + delta) + 'px';
tooltip.style.left = (e.pageX + delta) + 'px';
}
// get all elements that have an attribute from which we
// want to get the tooltip text from:
var toTitle = document.querySelectorAll('[' + textFrom + ']'),
//create a span element:
span = document.createElement('span'),
// find if we should use textContent or innerText (IE):
textProp = 'textContent' in document ? 'textContent' : 'innerText',
// caching variables for use in the upcoming forEach:
parent, spanClone;
// adding a class-name (for CSS styling):
span.classList.add('createdTooltip');
// iterating over each of the elements with a title attribute:
[].forEach.call(toTitle, function(elem) {
// reference to the element's parentNode:
parent = elem.parentNode;
// cloning the span, to avoid creating multiple elements:
spanClone = span.cloneNode();
// setting the text of the cloned span to the text
// of the attribute from which the text should be taken:
spanClone[textProp] = elem.getAttribute(textFrom);
// inserting the created/cloned span into the
// document, after the element:
parent.insertBefore(spanClone, elem.nextSibling);
// binding the reposition function to the mousemove
// event:
elem.addEventListener('mousemove', reposition);
// we're setting textFrom attribute to an empty string
// so that the CSS will still apply, but which
// shouldl still not be shown by the browser:
elem.setAttribute(textFrom, '');
});
}
// calling the function:

mouseover
上的标题并附加一个跨度。然后删除跨度并恢复标题
mouseout
