Question

有人能告诉我为什么这段代码不起作用吗？我叮叮当当＆＃34;检查拼写＆＃34;没有任何结果。我以前做过这样的事情并且工作正常。如果您有更好的建议，我可以告诉我。

的index.php：

<!DOCTYPE html>
<head>
    <title>Hi all</title>
<script type='text/javascript'>
    var doAction = function() {
        var text = document.getElementById("text").value;
        var language = document.getElementById("language").value;
        if(text != "") {
            var xmlhttp;

            if(window.XMLHttpRequest) {
                xmlhttp = new XMLHttpRequest();
            }
            else {
                xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
            } 

            var toSend = "text=" + text + "&language=" + language;

            xmlhttp.open("POST", "checking.php", true);
            xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
            xmlhttp.send(toSend);
            document.getElementById("ratespelling").innerHTML = "send.";
            xmlhttp.onreadystatechange = function() {
                if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                    if(xmlhttp.responseText != "") {
                        document.getElementById("ratespelling").innerHTML = "Your spelling is ?? accurate.";

                        document.getElementById("ctext").innerHTML = "Checked text: ".xmlhttp.responseText;
                    }
                    else {
                        document.getElementById("ctext").innerHTML = "Error.";
                    }
                }

            };
        }
        else {
            document.getElementById("ctext").innerHTML = "Text not found.";
        }
        return false;
    };

</script>
</head>
<body>
    <form onSubmit="return doAction();" id="schecking" method="post">
        <textarea name="text" rows=4 cols=40>Tekstas</textarea><br />
        <select name="language" form="schecking">
            <option value="en">English</option>
            <option value="fr">France</option>
            <option value="lt">Lithuanian</option>
            <option value="pl">Polish</option>
        </select>
        <input type="submit" name="checking" value="Check spelling">
    </form>
    <div id="ratespelling"></div><br />
    <div id="ctext"></div>
</html>
</body>

cheking.php

<?php
$text = explode(" ", $_POST['text']);
$language = $_POST['language'];
$pspell_link = pspell_new("en");
foreach($text as $word){
    if (pspell_check($pspell_link, $word)){
        echo $word;
    }else{
        echo "<span style="color:red">".$word."</span>";
    }
}
?>

Answer 1

我找到了一个:-)
改变这个：

<textarea name="text" rows=4 cols=40>Tekstas</textarea><br />
<select name="language" form="schecking">

到此：

<textarea id="text" name="text" rows=4 cols=40>Tekstas</textarea><br />
<select id="language" name="language" form="schecking">

Answer 2

您在这里传递ID值。

var text = document.getElementById("text").value;
var language = document.getElementById("language").value;

在表单中编辑，然后检查

<textarea name="text" id="text" rows=4 cols=40>Tekstas</textarea><br />
<select name="language" id="language" form="schecking">

我在任何地方都找不到错误？
