I created a JS and PHP code to query a database and display matching rows on a page. It was messing up other pages on WP, so I wanted to know how to target a single page so the JS doesn't run on other pages.
JS:
jQuery(document).ready( function() {
console.log("Document loaded");
jQuery("#searchButton").click( function(e) {
console.log("Search button clicked");
e.preventDefault();
var zipCode = document.getElementById("inputField").value;
var data = {
'action' : "zip_code",
'zip_code' : zipCode
};
console.log("Zip code entered: " + data.zip_code);
console.log("WP AJax URL: " + data.action);
jQuery.ajax({
type : "post",
dataType : "json",
url : data.action,
data : data,
success: function(response) {
console.log(response.data);
if(response.success) {
console.log("response.type == success");
jQuery("#results").html(response.data.data);
}
else {
console.log("response.type == else");
console.log(response.data);
}
},
error: function(errorThrown){
console.log("In error, error thrown!");
console.log(errorThrown);
}
})
})
});
PHP:
<?php
add_action( 'wp_enqueue_scripts', 'enqueue_parent_styles' );
function enqueue_parent_styles() {
wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
}
add_action('wp_ajax_zip_search', 'zip_search');
add_action('wp_ajax_nopriv_zip_search', 'zip_search' );
function zip_search()
{
global $wpdb;
// Functional code omitted for now. Just need to get "here" paragraph return (for now)
$output = "<p>here</p>";
$response = array(
'data' => $output,
);
wp_send_json_success($response);
}
add_action( 'wp_enqueue_scripts', 'my_load_scripts' );
function my_load_scripts() {
// Enqueue javascript on the frontend.
wp_enqueue_script(
'zip_js',
get_template_directory_uri() . '-child-agent_search/js/zip_search.js',
array('jquery')
);
// The wp_localize_script allows us to output the ajax_url path for our script to use.
wp_localize_script(
'zip_js',
'myAjax',
array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) )
);
}
?>

Reset to default 1Here, the code operates on anything that matches the #searchButton element:
jQuery("#searchButton")
If there is a searchButton on other pages, it will match it, soo you need to be more specific.
For example, on the homepage, the <body> tag will have the home class, here is my sites homepage body tag:
<body class="home blog logged-in admin-bar no-customize-support">
So to make it target only the search button on the home page, you could try something like this:
jQuery(".home #searchButton")
Alternatively, only enqueue the JS on that particular page, but the selector method is superior. Make sure there is only one element on the page with that ID as IDs need to be unique
#searchButton. Just don’t put that button on other pages and it won’t run. – Jacob Peattie Commented Jul 23, 2020 at 13:46
