right here is a block of my code. It works perfect in fireFox and Chrome. But not in IE. I get the error "Object doesn't support property or method 'includes'
"
function rightTreeSwapfunc2() {
if ($(".right-tree").css("background-image").includes("stage1") == true) {
$(".right-tree").css({
backgroundImage: "url(/plant-breeding/img/scenes/plant-breeding/stage5.jpg)"
})
} else {
$(".right-tree").css({
backgroundImage: "url(/plant-breeding/img/scenes/plant-breeding/stage3.jpg)"
})
}
}
I could change it up a bit and use vanilla JS and do:
document.getElementById("right-tree").classList.contains
But I would rather see if there is a way to get it to work in IE before changing the JS and editing the HTML and CSS.
If you look at the documentation of includes()
, most of the browsers don't support this property.
You can use widely supported indexOf()
after converting the property to string using toString()
:
if ($(".right-tree").css("background-image").indexOf("stage1") > -1) {
// ^^^^^^^^^^^^^^^^^^^^^^
You can also use the polyfill from MDN.
if (!String.prototype.includes) {
String.prototype.includes = function() {
'use strict';
return String.prototype.indexOf.apply(this, arguments) !== -1;
};
}
