我正在寻找一种在 html 页面正文中调用 javascript 编号的方法。这不一定是冗长和奢侈的只是简单的工作，我只想要这样的东西：
<html>
<head>
<script type="text/javscript">
var number = 123;
</script>
</head>
<body>
<h1>"the value for number is: " + number</h1>
</body>
</html>
如何在 html 正文中显示 javascript var

试试这个...
<html>
<head>
<script>
function myFunction() {
var number = "123";
document.getElementById("myText").innerHTML = number;
}
</script>
</head>
<body onload="myFunction()">
<h1>"The value for number is: " <span id="myText"></span></h1>
</body>
</html>使用 document.write()。
<html>
<head>
<script type="text/javascript">
var number = 123;
</script>
</head>
<body>
<h1>
the value for number is:
<script type="text/javascript">
document.write(number)
</script>
</h1>
</body>
</html><html>
<head>
<script type="text/javascript">
var number = 123;
var string = "abcd";
function docWrite(variable) {
document.write(variable);
}
</script>
</head>
<body>
<h1>the value for number is: <script>docWrite(number)</script></h1>
<h2>the text is: <script>docWrite(string)</script> </h2>
</body>
</html>
你可以缩短document.write但不能避免<script>标记
您可以对文档ready事件执行相同的操作，如下所示
<script>
$(document).ready(function(){
var number = 112;
$("yourClass/Element/id...").html(number);
// $("yourClass/Element/id...").text(number);
});
</script>
或者您可以简单地使用document.write(number);.
<script type="text/javascript">
function get_param(param) {
var search = window.location.search.substring(1);
var compareKeyValuePair = function(pair) {
var key_value = pair.split('=');
var decodedKey = decodeURIComponent(key_value[0]);
var decodedValue = decodeURIComponent(key_value[1]);
if(decodedKey == param) return decodedValue;
return null;
};
var comparisonResult = null;
if(search.indexOf('&') > -1) {
var params = search.split('&');
for(var i = 0; i < params.length; i++) {
comparisonResult = compareKeyValuePair(params[i]);
if(comparisonResult !== null) {
break;
}
}
} else {
comparisonResult = compareKeyValuePair(search);
}
return comparisonResult;
}
var parcelNumber = get_param('parcelNumber'); //abc
var registryId = get_param('registryId'); //abc
var registrySectionId = get_param('registrySectionId'); //abc
var apartmentNumber = get_param('apartmentNumber'); //abc
</script>然后在页面中，我像这样调用值：
<td class="tinfodd"> <script type="text/javascript">
document.write(registrySectionId)
</script></td>
