php - 使用 JavaScript 提交表单的问题

Question

我想提交一个基于ajax响应的PayPal表单。问题是 ajax 部分工作正常，但表单仍然没有提交。

首先，我在表单中使用按钮(而不是提交按钮)。在该按钮上，将调用 JavaScript 函数，如果 ajax 响应是肯定的，则表单将被提交。

这是我的脚本

<script>
function mustvalid() {

    var company_name = document.forms["cord_form"]["company_name"].value;
    var slogan = document.forms["cord_form"]["slogan"].value;
    var cord_email = document.forms["cord_form"]["cord_email"].value;
    var company_do = document.forms["cord_form"]["company_do"].value;
    var brand_color = document.forms["cord_form"]["brand_color"].value;
    var imaginary = document.forms["cord_form"]["imaginary"].value;
    var ex_logo = document.forms["cord_form"]["ex_logo"].value;

    alert('hiidoooo');

    $.post("<?php echo base_url();?>ajax/set_custom_order", {
        'company_name': company_name,
            'slogan': slogan,
            'cord_email': cord_email,
            'company_do': company_do,
            'brand_color': brand_color,
            'imaginary': imaginary,
            'ex_logo': ex_logo
    },

    function (data) {
        if (data == "done") {
            alert(data);
            document.getElementById('cord_form').submit();
            // this line isnt working so the alert following this line is also not working;
            alert('hmm');
        } else {
            alert('hii');
        }
    });
}    
</script>

<div class="pitch single">
        <h1>Custom Order</h1>

    <!--<?php echo $cms[0]['content_desc']; ?>-->
</div>
<div id="top_adv">
    <?php echo $top_adv; ?>

        </div>
        <img src="<?=site_url('home/securimage')?>" title="captcha" id="captcha2" />
        <input type="text" name="captcha_code" size="10" maxlength="6" />   <a href="#" onclick="document.getElementById('captcha2').src = '<?=site_url('home/securimage')?>?' + Math.random(); return false">[ Different Image ]</a>

        <br/>
        <?php echo @$_SESSION[ 'ctform'][ 'captcha_error'] ?>
        <br/>
        <input type="hidden" name="amount" value="$10">
        <input type="hidden" name="lc" value="US">
        <input type="button" value="Send" name="submit" class="contact_submit" onclick="mustvalid()" />
    </form>

我只是不知道这里有什么错误。

尝试将按钮的名称更改为“提交”以外的名称。 It might be causing a conflict 。既然您使用的是 jQuery，为什么不将您的行更改为:

$("#cord_form").submit();
