I need to exchange two href if a "text" is exact. I tried lots of solutions and I thought I finally found one with a clean way but there is no change and no error. Do you have an explanation ?
let link_1 = document.getElementById('rempl_1').href;
let link_2 = document.getElementById('rempl_2').href;
$(document).ready(function() {
if (
document.getElementById('custom_field').innerHTML.indexOf('remplacement') != -1) {
let tmp = link_1;
link_1 = link_2;
link_2 = tmp;
}
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<div class="row">
<span class="custom_field" id="custom_field">remplacement</span>
<a class="rempl" href="my_first_url" title="original" id="rempl_1">First</a>
<a class="rempl" href="my_second_url" title="remplacement" id="rempl_2">Second</a>
</div>You mean this?
Note I removed the need for jQuery since you were not using it anyway
window.addEventListener("load", function() {
const custom = document.getElementById('custom_field');
if (custom.innerHTML.includes('remplacement')) {
const links = document.querySelectorAll(".rempl");
const href0 = links[0].href;
const href1 = links[1].href;
links[0].href = href1;
links[1].href = href0;
}
});<div class="row">
<span class="custom_field" id="custom_field">remplacement</span>
<a class="rempl" href="my_first_url" title="original" id="rempl_1">First</a>
<a class="rempl" href="my_second_url" title="remplacement" id="rempl_2">Second</a>
</div>string is copied as value when assigned to new variable, so assign a new string to variable will not change href original value.
if change anchor href is what you want, you should add
document.getElementById('rempl_1').href = link_1;
document.getElementById('rempl_2').href = link_2;
for this scenario, i prefer store element as variable:
let a1 = document.getElementById('rempl_1');
let a2 = document.getElementById('rempl_2');
$(document).ready(function () {
if (
document.getElementById('custom_field').innerHTML.includes('remplacement')
) {
[a1.href, a2.href] = [a2.href, a1.href];
}
});
PS: maybe you want write replacement instead of remplacement
