I'm trying to replace all img src's on my page, when they have a certain url in them. So far I'm able to log all the replaced img src's, but my final step would be to change them on my page.
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;
See my pen: https://codepen.io/kleefaan/pen/yqzBVv
Instead of pushing all elements into an array you can do the replace in the for loop like this:
// 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);
}
