PHP与JS交互
JS年闰年判断(body里直接引用JS)
<form name="form1" method="post" action="">
<span class="style2">Jian Ce Run Nian:</span>
<select name="year">
<option value="2000">2000</option>
<option value="2008">2008</option>
<option value="2009">2009</option>
</select>
<input type="submit" name="Submit" value="Jian Ce" οnclick="check()">
</form>
<script language="javascript">
function check(){
var y1=form1.year.value;
if(((y1 % 4 == 0) && (y1 % 100 != 0)) || y1 % 400 == 0){
alert(y1+"Nian Shi Run Nian");
}else{
alert(y1+"Nian Bu Shi Run Nian");
}
}
</script>
<?PHP
echo "lalala";
?>
SWITCH
<script language="javascript">
function check(books){
switch (books) {
case "1":
alert("11111");
break;
case "2":
alert("22222");
break;
case "3":
alert("33333");
break;
case "4":
alert("44444");
break;
case "5":
alert("55555");
break;
}
}
</script>
<body>
<form name="form1" method="post" action="">
<span class="style2">Ni Zui Xi Huan De Tu Shu Lei Bie:</span>
<input name="book" type="radio" value="1" οnclick="check(this.value)">1
<input name="book" type="radio" value="2" οnclick="check(this.value)">2
<input name="book" type="radio" value="3" οnclick="check(this.value)">3
<input name="book" type="radio" value="4 οnclick="check(this.value)">4
<input name="book" type="radio" value="5" οnclick="check(this.value)">5
</form>
</body>
While
<script language="JavaScript" type="text/javascript">
var i = 3;
while(i > 0){
document.write("-"+i);
i --;
}
</script>
For
<script language="JavaScript">
for(var i = 0 ;i < 20 ;i ++){
if(i > 10){
break;
}
document.write(i+"-");
}
</script>
JavaScript常用事件
HTML嵌入JS
<html>
<head>
<title>JS</title>
</head>
<body>
<script language="JavaScript">
alert("lalala");
</script>
</body>
</html>
PHP中添加JS文件
<script src="j.js" language="JavaScript"></script>
<?php
?>
处理浏览器是否支持JS问题
<html>
<head>
<title>Pan Duan Shi Fou Zhi Chi JS</title>
</head>
<body>
<script language="JavaScript">
<!--
document.write("Nin De Liu Lan Qi Zhi Chi JS");
-->
</script>
<noscript>
Nin De Liu Lan Qi Bu Zhi Chi JS
</noscript>
</body>
</html>
JS事件
<table width="761" height="20" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="75" align="center"><a href="#" onMouseMove="LL('1')">111</a></td>

break;
case "2":
document.write("222");
break;
case "3":
document.write("444");

}
}
</script>
PHP时间
<?PHP
$time1 = strtotime(date("Y-m-d H:i:s"));
$time2 = strtotime("2017-2-24 17:10:00");
$time3 = strtotime("2017-2-23");
$sub1 = ceil(($time2-$time1));
$sub2 = ceil(($time3-$time1));
echo "<font color='red'> $sub1</font>";
echo "<p>";
echo "<font color='red'> $sub2</font>";
?>
