表格提交成功后自动下载PDF文件

Question

我对BackboneJS很新。提交表单后，我需要自动下载PDF文件。 PDF可以是静态链接或静态路径。请帮助我实现这些人，因为我有不眠之夜:(

我可以提交表格并获得感谢页面。但我需要在提交后下载文件，

   <form id="contactForm1" name="consultData" data-toggle="validator" 
    role="form" >
                    <div class="row">
                        <div class="form-group">
                            <input type="text" class="form-control" 
     placeholder="Name*" id="contact_full_name1" name="fullName" value="
     <%=userProfile ? userProfile.displayName : ''%>" required/>
                            <span class="glyphicon form-control-
         feedback" aria-hidden="true"></span>
                            <div class="help-block with-errors  
              text-left"></div>
                        </div>
                        <div class="form-group">
                            <input type="email" class="form-control" 
      placeholder="Email*" id="contact_email_id1" name="email" value="
      <%=userProfile ? userProfile.email : ''%>" required 
      pattern=".+@.+\..+" title="<abc>@<xyz>.<com>"/>
                            <div class="help-block with-errors 
                text-left"></div>
                        </div>
                        <div class="form-group has-feedback">
                            <input type="text" class="form-control" 
       id="contact_contact_num1" placeholder="Contact Number*" value="
     <%=userProfile ? userProfile.phone : ''%>" required  
        pattern="\d{10}" title="e.g. 9876543210"/>
                            <div class="help-block with-errors 
         text-left"></div>
                        </div>
                        <div class="form-group">
                            <select class="form-control"  
        id="contact_city">
                                <option> City </option>
                                <option> Bangalore </option>
                                <option> Mangalore </option>
                                <option> Pune </option>
                            </select>
                        </div>
                        <div class="form-group">
                            <button id="contactus-submit-btn1"  
       class="btn btn-default btn-block btn-kitchen" type="submit" 
       data-loading-text="<i class='fa fa-spinner fa-spin'></i> submit">
                                submit
                            </button>
                        </div>
                    </div>
                </form>

这是js，
