I know you can add readonly="readonly" to an input field so its not editable. But I need to use javascript to target the id of the input and make it readonly as I do not have access to the form code (it's generated via marketing software)
I don't want to disable the input as the data should be collected on submit.
Here is the page I have added in the below suggestion with no luck so far:

Make sure you use <body onload="onLoadBody();"> for anyone using this in the future.
You can get the input element and then set its readOnly property to true as follows:
document.getElementById('InputFieldID').readOnly = true;
Specifically, this is what you want:
<script type="text/javascript">
function onLoadBody() {
document.getElementById('control_EMAIL').readOnly = true;
}
</script>
Call this onLoadBody() function on body tag like:
<body onload="onLoadBody">

The above answers did not work for me. The below does:
document.getElementById("input_field_id").setAttribute("readonly", true);
And to remove the readonly attribute:
document.getElementById("input_field_id").removeAttribute("readonly");
And for running when the page is loaded, it is worth referring to here.
document.getElementById("").readOnly = true
document.getElementById('TextBoxID').readOnly = true; //to enable readonly
document.getElementById('TextBoxID').readOnly = false; //to disable readonly
Try This :
document.getElementById(<element_ID>).readOnly=true;
I think you just have readonly="readonly"
<html><body><form><input type="password" placeholder="password" valid="123" readonly=" readonly"></input>
Here you have example how to set the readonly attribute:
<form action="demo_form.asp">
Country: <input type="text" name="country" value="Norway" readonly><br>
<input type="submit" value="Submit">
</form>
