[英]convert a text link to image link
I am in the middle of making a post system for my website, and i would like some javascript that would turn a text link like 我正在为我的网站制作一个帖子系统,我想要一些可以打开文本链接的JavaScript,例如
<a href="path/to/image.jpg">Image</a>
into <a href="path/to/image.jpg">Image</a>
<a href="path/to/image.jpg"><img src="path/to/image.jpg" /></a>
but only turn it into an image link when something such as a regex recognises that the link is to an image. 但只有当诸如正则表达式之类的东西识别出该链接是指向图像时,才将其转换为图像链接。
Or i dont mind doing something like adding a data-type="image" attribute to the link, but i still need the code to turn it into an image link. 或者我不介意做一些类似向链接添加data-type =“ image”属性的操作,但是我仍然需要代码将其转换为图像链接。
$('a[href$=".png"], a[href$=".jpg"], a[href$=".gif]"').each(function(){
$(this).html('<img src="' + $(this).attr('href') + '" />');
});

I'd recommend putting a class on all of the anchors links you want to convert. 我建议您在要转换的所有锚链接上放置一个类。 Let's say you choose to use a convert
class. 假设您选择使用convert
类。 Then, you could use jQuery the add an img
tag inside the anchor tag: 然后,您可以使用jQuery在anchor标签内添加img
标签:
// for each anchor that needs converting
$('.convert').each(function() {
// get the href of the anchor
var href = $(this).attr('href');
// create the string we want to append to the anchor
var imgString = '<img src="' + href + '" alt="" />';
// and then append it
$(this).append(imgString);
});
@Alex solution is a better one, but if you could not add a class @Alex解决方案是更好的解决方案,但是如果您不能添加一个类
$('a').each(function(){
var a = $(this)
if(a.text() == 'Image')
a.html('<img src="'+a.href+'" >')
})
