这是我的整个 html 页面
<html>
<head>
<title> text conversion</title>
<script type="text/javascript">
function testResults(form)
{
var str = form.stringn.value;
str.split(" ");
document.write("testing1");
var length = str.length;
var newn = "";
for(var i = 0; i<length; i++)
{
if(str[i].charAt(str[i].length - 1) != ".")
{
str[i] = str[i] + ".";
}
str[i] = str[i] + " ";
str[i].charAt(0) = str[i].charAt(0).toUpperCase();
newn = newn + str[i];
}
document.write(newn);
document.write("testing");
}
</script>
</head>
<body>
<form name="stringform" action="" method="get">
Text: <input type="text" name="stringn"><br>
<input type="button" name="Convert" Value="convert" onClick="testResults(this.form)">
</form>
</body>
</html>
html 正在正确显示,但按钮不产生任何动作。我什至在 javascript 中的循环下方尝试了 document.write("testing"),但没有任何效果,这让我认为该函数根本没有被调用。该函数的思想是将输入字符串格式化为每个单词的首字母大写,并在每个单词后面加上句点。
这是我第一次尝试使用 javascript,所以可能我做错了什么应该很明显?
最终解决方案:
<html>
<head>
<title> text conversion</title>
<script type="text/javascript">
function testResults(form)
{
var str = form.stringn.value;
var strn = str.split(" ");
var length = strn.length;
var newn = "";
for(var i = 0; i<length; i++)
{
if(strn[i].charAt(strn[i].length - 1) != ".")
{
strn[i] = strn[i] + ".";
}
strn[i] = strn[i].charAt(0).toUpperCase() + strn[i].slice(1);
strn[i] = strn[i] + " ";
newn = newn + strn[i];
}
document.write(newn);
}
</script>
</head>
<body>
<form name="stringform" action="" method="get">
Text: <input type="text" name="stringn"><br>
<input type="button" name="Convert" Value="convert" onClick="testResults(this.form)">
