6.PHP与JavaScript交互
PHP與JS交互
JS年閏年判斷(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
?>
?
處理瀏覽器是否支持JS問題
<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>
????????<td?width="75"?align="center"><a?href="#"?onMouseMove="LL('2')">222</a></td>
????????<td?width="75"?align="center"><a?href="#"?onMouseMove="LL('3')">333</a></td>
????</tr>
</table>
<script?language="JavaScript">
????function?LL(V){
????????switch?(V){
????????????case?"1":
????????????????document.write("111");
????????????????break;
????????????case?"2":
????????????????document.write("222");
????????????????break;
????????????case?"3":
????????????????document.write("444");
????????????????break;
????????????default:
????????????????alert("444");
????????}
????}
</script>

PHP時間
<?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>";
