生成动态URL并将表单方法设置为Post

Question

我正在根据用户输入生成一个URL，并且html和java脚本在同一个文件中，java脚本函数在脚本标记中，

<form name="generate" action="javascript:openUrl" method="post" onSubmit="return createUrl()">
  <table>
    <tr><td>Select Instance :</td>
      <td>

      </td>
    </tr>
    <tr><td style="padding-bottom: 10px;">Email : </td><td><input type="text" style="width:300px;" name="email" ng-model="email" class="ticker-textbox" /></td></tr>
    <tr><td style="padding-bottom: 10px;">Expiration Date: </td><td><input type="text" style="width:150px;" name="expiryDate" class="ticker-textbox" />mm/dd/yyyy</td></tr>
    <tr><td style="padding-bottom: 10px;">First Name : </td><td><input type="text" style="width:300px;" name="firstName" class="ticker-textbox" /></td></tr>
    <tr><td style="padding-bottom: 10px;">Last Name : </td><td><input type="text" style="width:300px;" name="lastName" class="ticker-textbox" /></td></tr>
    <tr><td style="padding-bottom: 10px;">Generated URL :</td><td><input disabled type="text" style="width:800px;" name="genURL" class="ticker-textbox" /></td></tr>
    <tr>
      <td><input type="button" name="button" value="Generate URL" onclick="createUrl()"/></td>
      <td><input type="button" name="open" value="Open URL" onclick="openUrl()"/></td>
    </tr>
  </table>
</form>

我无法将方法设置为POST，无论如何，它都将方法设置为GET。

我尝试使用jquery在创建URL函数中设置$ .post，但它表示$无法识别。

功能：

 var createUrl = function () {

             var url = document.generate.instance.value + '/user/remoteLogin.html?clientName=' + cn;

             if (hasText(document.generate.expiryDate.value)) {
               var expiryDate = urlEncode(document.generate.expiryDate.value);
               url += ('&expirationDate=' + expiryDate);
               window.key = window.key.substring(0, window.key.length - document.generate.expiryDate.value.length)
               window.key += document.generate.expiryDate.value;
             }

             var decodedKey = decodeBase64(window.key);
             if (hasText(document.generate.email.value)) {
               var em = urlEncode(encrypt(decodedKey, document.generate.email.value));
               em = em.trim();
               url += ('&em=' + em);

             }

             if (hasText(document.generate.firstName.value)) {
               var fn = urlEncode(encrypt(decodedKey, document.generate.firstName.value));
               url += ('&fn=' + fn);
             }

             if (hasText(document.generate.lastName.value)) {
               var ln = urlEncode(encrypt(decodedKey, document.generate.lastName.value));
               url += ('&ln=' + ln);
             }

             document.generate.genURL.value = url;

             return true;
           }

         }
         var openUrl = function () {

             location.href = document.generate.genURL.value;

             return false;
           }
         }
