Aaargh。我写了一个简单的HTML页面,上面有一个表格来接收电话号码。我输入了一个Javascript函数,一旦它满了就会使焦点跳转到下一个表格框。一切似乎都很完美。
然而,由于某种原因,它无法正常工作。我不明白为什么,因为我创建了一个几乎相同的文件只有表单和功能,它的工作原理!所以这个特定文件中的某些内容阻止它,但经过30分钟的修补后我无法弄清楚是什么。
<html>
<head>
<script type="text/javascript">
function moveToNext(curr, next) {
if(curr.value.length == curr.getAttribute("maxlength"))
next.focus();
}
</script>
<title> Enter Phone Number </title>
<style type="text/css">
#content {
background:url(images/content-bg-rpt.gif) repeat;
margin: 0 auto;
height: 300px;
width: 500px;
}
#formArea {
margin-top: 50px;
width: 250px;
margin-left: auto;
margin-right: auto;
}
#submit {
position: relative;
}
.formInput { /* These are the input styles used in forms */
background: #f7f7f7 url(../img/input.gif) repeat-x;
border: 1px solid #d0d0d0;
margin-bottom: 6px;

两件事:
onkeyup
属性有两个右括号和一个开头括号。.formInput
。这解决了我的两个问题:
<input onkeyup="moveToNext(this, document.enterPhone.d345)" type="text" class="formInput" maxlength="3" size="3" name="d012" id="d012"></input>
<input onkeyup="moveToNext(this, document.enterPhone.d6789)" type="text" name="d345" class="formInput" maxlength="3" size="3" id="d345"></input>

使用此 jsFiddle example
修复了您的代码<强> HTML 强>
<div id="container">
<div id="content">
<div id="formArea">
<form name="enterPhone" id="enterPhone" action="phoneresult.php" method="GET">
<input onkeyup="moveToNext(this, document.getElementsByName('d345'))" type="text" class="formInput" maxlength="3" size="3" name="d012" id="d012"></input>
<input onkeyup="moveToNext(this, document.getElementsByName('d6789'))" type="text" name="d345" class="formInput" maxlength="3" size="3" id="d345"></input>
<input type="text" class="formInput" maxlength="4" size="4" name="d6789"></input>
<input id="submit" value="Enter" type="submit"></input>
</form>
</div>
</div>
</div>
<强>的JavaScript 强>
function moveToNext(curr, next) {
if (curr.value.length == parseInt(curr.getAttribute("maxlength"), 10)) next[0].focus();
}
在你的JS中,你在整数和字符串(curr.value.length == curr.getAttribute("maxlength")
)之间进行比较。在您的HTML中,您没有使用document.enterPhone.d345.formInput
正确选择元素。

function moveToNext(curr, next) {
if (curr.value.length >= curr.maxLength) {
document.getElementById(next).focus();
}
}
<强> HTML 强>
<form name="enterPhone" id="enterPhone" action="phoneresult.php" method="GET">
<input onkeyup="moveToNext(this, 'd345')" type="text" class="formInput" maxlength="3" size="3" name="d012" id="d012"/>
<input onkeyup="moveToNext(this, 'd6789')" type="text" name="d345" class="formInput" maxlength="3" size="3" id="d345"/>

试试这个,用下面的代码替换三个输入标签:
<input onkeyup="moveToNext(this, document.enterPhone.d345)" type="text" class="formInput" maxlength="3" size="3" name="d012" id="d012"></input>
<input onkeyup="moveToNext(this, document.enterPhone.d6789)" type="text" name="d345" class="formInput" maxlength="3" size="3" id="d345"></input>
<input type="text" class="formInput" maxlength="4" size="4" name="d6789" id="d6789"></input>
