window.location.href是位置对象的javascript属性，因此需要将其连接到值字符串，以便在字符串中应用其值，并且最好引用该值：

jQuery(document).ready(function($){
   $('select').find('option[value="'+ window.location.href+'"]')
              .attr('selected','selected');
});

示例：

var locationHrefMock = "http://www.test.com/page5" ;
jQuery(document).ready(function($){
   $('select').find('option[value="'+ locationHrefMock +'"]')
              .attr('selected','selected');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select>
   <option value="http://www.test.com/page0">Japanese yen (JPY)</option>
<option value="http://www.test.com/page1">Afghan afghani (AFN)</option>
<option value="http://www.test.com/page2">Albanian lek (ALL)</option>
<option value="http://www.test.com/page3">Algerian dinar (DZD)</option>
<option value="http://www.test.com/page4">Angolan kwanza (AOA)</option>
<option value="http://www.test.com/page5">Argentine peso (ARS)</option>
<option value="http://www.test.com/page6">Armenian dram (AMD)</option>
<option value="http://www.test.com/page7">Aruban florin (AWG)</option>
<option value="http://www.test.com/page8">United States dollar (USD)</option>
</select>
