当它们中有特定的URL时,我正在尝试替换页面上的所有img src。到目前为止,我已经能够记录所有替换后的img src,但是我的最后一步将是在页面上进行更改。
function replaceMyImgs() {
// put live url here
var liveUrl = "via.placeholder.com";
// find the local url
var localUrl = "testdomain.com";
// replace the local url for the live url
var newUrl = localUrl.replace(/testdomain.com/g, liveUrl);
// console.log(newUrl);
// get all images and push them in an empty array
var imgs = document.getElementsByTagName("img");
var imgSrcs = [];
for (var i = 0; i < imgs.length; i++) {
imgSrcs.push(imgs[i].src);
}
imgSrcs.forEach(function(src) {
// log all the found img srcs
var newSrc = src.replace(/testdomain.com/g, liveUrl);
imgs.src = newSrc;
console.log(imgs.src);
});
}
window.onload = replaceMyImgs;

您可以像下面这样在for循环中进行替换,而不是将所有元素都放入数组中:
// get all images
var imgs = document.getElementsByTagName("img");
for (var i = 0; i < imgs.length; i++) {
var newSrc = imgs[i].src.replace(/testdomain.com/g, liveUrl);
imgs[i].src = newSrc;
console.log(imgs[i].src);
}
