I am noob in coding in JS and SharePoint, I've to check two conditions in NewForm.aspx.
If field, for e.g. "Name" has value "Test", and field "Second Name" has value "Test", then I want field named "Result" to be visible. If values from this two mentioned fields are different, then the field "Result" needs to be hidden.
Try adding below code to your NewForm.aspx using Content Editor or Script Editor web part:
<script type="text/javascript" src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('nobr:contains("Result")').closest('tr').hide();
//Show/hide columns based on "Name" column
$("input[title^='Name']").change(function () {
var secondNameVal = $("input[title^='Second Name']").val();
if ($(this).val() != secondNameVal) {
$('nobr:contains("Result")').closest('tr').hide();
} else {
$('nobr:contains("Result")').closest('tr').show();
}
});
//Show/hide columns based on "Second Name" column
$("input[title^='Second Name']").change(function () {
var nameVal = $("input[title^='Name']").val();
if ($(this).val() != nameVal) {
$('nobr:contains("Result")').closest('tr').hide();
} else {
$('nobr:contains("Result")').closest('tr').show();
}
});
});
</script>
