JQuery：将焦点设置在特定页面上的输入字段上

Question

I am trying to set focus on Customer Name only on the search_orders.php page. The code below is supposed to put the cursor in the Name input if on the order search page. Somehow this doesn't work. Please suggest any change to my code that will fix this. Attached is the UI for searching orders, where I need the focus set on Customer Name.

function po_number_first(){
   if (document.location.href.indexOf("search_orders")==-1){
      document.search_form.po_number.focus();
}else{
     document.getElementById("Name").focus();
}
}

The function call is in a smartyTemplate files as seen in the code below.

{include file="header.tpl" page_name=Search extra_javascript='<script language="JavaScript" src="includes/search_orders.js"></script>' on_load_script='po_number_first()'}

Instead of adding it inside a function please try:-

jQuery(document).ready(function() {
   if ( window.location.href.indexOf('/search_orders') > -1 ) {
     jQuery( "#target" ).focus();
   }else{
     jQuery( "#Name" ).focus();
   }
});
