6.PHP与JavaScript交互

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>
        <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>";
?>
