jQuery replace text of element on hover
提问by cusejuice
With jQuery, I'm trying to replace the text, including the span, inside these links on hover. Then when the user hover's off, the original text is displayed again.

<a class="btn" href="#">
<img src="#" alt=""/>
<span>Replace me</span> please
</a>
The final output should be

$('.btn').hover(
function() {
var $this = $(this); // caching $(this)
$this.data('defaultText', $this.text());
$this.text("I'm replaced!");
},
function() {
var $this = $(this); // caching $(this)
$this.text($this.data('defaultText'));
}
);
you could save the original text in a data-defaultTextattribute stored in the node itself so to avoid variables
您可以将原始文本data-defaultText保存在存储在节点本身的属性中，以避免变量

$(this).text("I'm replaced!");

You'd need to store it in a variable in order to set it back to what it was, try:
您需要将它存储在一个变量中以将其设置回原来的状态，请尝试：
var text;
$(".btn").hover(function () {
text = $(this).text();
$(this).text("I'm replaced!");
},
function () {
$(this).text(text);
});
