Do you have an address you could share?

<script type=”text/javascript”>
jQuery(document).ready(function() {
jQuery(“input[placeholder=’search’]”).attr(“placeholder”, “Your Text”);
}
</script>

Put this scrip either at the bottom of the page where you have this search field.
Or, if this field is on every page, place it in header, or footer.
Cheers!

This is what I need to change. “Any text” in place holder
<input type=”text” value=”” placeholder=”any text” autocomplete=”off”>

Here is the script again:
<script type=”text/javascript”>
jQuery(document).ready(function() {
jQuery(“input[placeholder=’search’]”).attr(“placeholder”, “any text”);
}
</script>

Assuming you’re changing a placeholder named “search” with “any text”.

There are easier ways to make changes depending on if the search box you are using is a part of a plugin, the default WP search or something custom.

If you can share the address of the page you are trying to modify or at the very least a screenshot, it makes it far easier to give an answer specific to your situation.
