无法将PHP响应文本返回到HTML div。我通过AJAX成功地将一个变量发送到PHP表单但是在我的生活中无法弄清楚如何在不使用Alert的情况下将其注入Success div。我究竟做错了什么?谢谢!
在此处表格:
<form name="codesubmit" id="codesubmit">
<div class="field">
<font color="black"><label for="codeentry">Unique Code:</label></font>
<input pattern=".{5,5}" class="form-control" type="text" id="codeentry" name="codeentry" maxlength="5" title="Enter 5-character unique code." required>
</div>
<div class="rsvp-button text-center"><button type="submit" class="hvr-sweep-to-right">Submit</button>
<div id="loding" style="display:none; padding-left:20px;"><img src="images/ajax-loader.gif" alt="Loader"></div></div>
</form>
<div id="Success" class="successalert" style=" display:none;"> <strong>Thank you</strong>.
<p>ENTER RETURN VAR INFO HERE.</p></div>
<div id="Error" class="errorelert" style="display:none;"> <strong>Something went wrong, contact Ben Taylor please.</strong></div>
JS在这里:
(function ($) {
'use strict';
$("#codesubmit").submit(function (event) {
event.preventDefault();
$("#loding").css("display", "inline-block");
$.post("codesubmit.php", {
UniqueCode: $("#codeentry").val()
})
.done(function (data) {
if (data) {
$("#loding").hide();
$("#Success").slideDown("slow");
//document.write("Test");
$("#codesubmit")[0].reset();
}
else {
$("#loding").hide();
$("#Error").slideDown("slow");
setTimeout(function () {
$("#Error").slideUp("slow");
}, 30000);
}
});
});
})(jQuery);
PHP在这里:
<?php
// Only process POST reqeusts.
if ($_SERVER["REQUEST_METHOD"] == "POST") {
// Get the form fields and remove whitespace.
$codeentry = trim($_POST["UniqueCode"]);
// Testing: Send Back Code.
echo $codeentry; ?>

在.done(...)回调中,您会看到&#34;数据&#34;参数,具有您从PHP回显的内容。我建议获取数据中的值并将其存储在&#34; p&#34;您在表单中使用的标记,如下所示:
int step_1= fmax(a[0], a[1]);
int step_2 = fmax(a[2], a[3]);
int step_3 = fmax(step_1, a[4]);
int step_final = fmax(step_3, step_2);
cout<<step_final;
然后在JS:
<div id="Success" class="successalert" style=" display:none;">
<strong>Thank you</strong>.
<p id="some_id">ENTER RETURN VAR INFO HERE.</p>
</div>
