Question

我发送给UPS的以下脚本，UPS页面计算运费。

<script type="text/javascript">
$('#shipping').submit(function(e){
  var url = [
    "http://www.ups.com/using/services/rave/qcostcgi.cgi?accept_UPS_license_agreement=yes",
    "10_action=3",
    "13_product="+ $('* [name="selService"]').val(),
    "14_origCountry="+ $('* [name="txtFromCountry"]').val(),
    "15_origPostal="+ $('* [name="txtFromZip"]').val(),
    "origCity="+ $('* [name="txtFromCity"]').val(),
    "19_destPostal="+ $('* [name="txtToZip"]').val(),
    "20_destCity="+ $('* [name="txtToCity"]').val(),
    "22_destCountry="+ $('* [name="txtToCountry"]').val(),
    "23_weight="+ $('* [name="txtPackWeight"]').val(),
    "47_rateChart="+ $('* [name="selRate"]').val(),
    "48_container="+ $('* [name="selPackaging"]').val(),
    "49_residential="+ $('* [name="selResidential"]').val(),
    "25_length="+ $('* [name="txtPackLength"]').val(),
    "26_width="+ $('* [name="txtPackWidth"]').val(),
    "27_height="+ $('* [name="txtPackHeight"]').val()
  ].join('&');

  window.open(url); //you want to split output by '%' for it to make sense
  e.preventDefault();
});
</script>

如何让它将生成的运费值返回给我的脚本。在PHP中我会使用类似的东西：

  $fp = fopen($url, "r");
  while(!feof($fp)){
    $result = fgets($fp, 500);
    $result = explode("%", $result);
    $errcode = substr($result[0], -1);
    switch($errcode){
      case 3:
        $returnval = $result[8];
            break;
    }
  }

但我正在尝试这样做100％javascript / Jquery。请帮忙。

Answer 1

而不是做window.open（url）;

你只是使用一个ajax函数，看起来你想要查看正在生成的url的get请求...

https://api.jquery.com/jQuery.get/

$.ajax({
  url: url,
  success: function(data) {
    // data is the returned data
  }
});

Answer 2

如果您遇到安全问题，则无法向其他域“ups.com”发出请求，如果您出现以下错误

  XMLHttpRequest cannot load http://www.ups.com/usin... 
  No 'Access-Control-Allow-Origin' 
  header is present on the requested resource. 
  Origin 'null' is therefore not allowed access.

研究“跨站点脚本”一词。
