$ .post不发布任何东西 [英] $.post not POSTing anything

问题描述

我正在使用以下jquery将评论发布到user_submit.php

i am using the following jquery to post comments to user_submit.php

var submit = document.getElementById("submit_js");
    var comment = document.getElementById("comment");

    $("#submit").bind('click', function(){
        $.post("user_submit.php", {
            comment: $("#comment").text()
        });
    });

user_submit.php的监听方式如下:

the user_submit.php listens like:

$comment = htmlspecialchars($_POST["comment"]);

我可以在Firebug控制台中看到没有POST发生.我只有一个用于其他功能的GET(这可能是罪魁祸首吗?)

i can see in the Firebug console that there is no POST happening. only a single GET that i use for a different function (can this be the culprit?)

推荐答案

假设:

<input type="text" id="comment">
<input type="button" id="submit_js">

您想要的:

$(function() {
  $("#submit_js").click(function() {
    $.post("user_submit.php", {
      comment: $("#comment").val()
    });
  });
});

PHP:

<?php
$comment = $_POST['comment'];
//...
echo htmlspecialchars($comment); // nothing catches this currently
?>

您似乎还在代码中混淆了"submit"和"submit_js".我也建议不要不必要地混合Javascript和jQuery代码("getElementById()"业务).您应该熟悉 jQuery选择器.例如:

You also seem to be confusing "submit" and "submit_js" in your code. I'd advise against mixing Javascript and jQuery code unnecessarily too (the "getElementById()" business). You should familiarize yourself with jQuery selectors. For example:

$("#submit_js")

将使用ID为submit_js的所有元素(应该只能为零或一个元素)创建一个jQuery对象.

will create a jQuery object with all the elements (which should only be zero or one elements) with the ID of submit_js.
