<br>
<input type="submit" name="submit" id="submit" value="enable" onclick="enable()"  > 

</body>
</html>

can anyone suggest how to get it.?

Answer 1

我认为你可以设置

var x = document.getElementById("button").setAttribute("value", "enable");

就像那样，您可以访问该特定变量并编辑它的能力。

使用javascript，您可以将按钮的能力值传递给第二个PHP页面。

Answer 2

page2.php中的

内部功能启用获得临时值后

if(temp){
    document.getElementById("myBtn").disabled = true;
} else {
    document.getElementById("myBtn").disabled = false;
}

Answer 3

试试这个：

注意：请阅读代码中的注释以获取更多说明。

page1.php 和 page2.php 将包含以下JS代码：

<script type="text/javascript">
function enable(){
    // Set enable/disable in session to be read on next page and this page on refresh
    var xhttp = new XMLHttpRequest();
    xhttp.open("GET", "setButtonStatus.php", true);
    xhttp.send();

    // set enable/disable value for current event
    if(this.value == 'enable'){
        this.value = 'disable';   
    } else {
        this.value = 'enable';
    }
}
</script>

在 setButtonStatus.php

中

<?php
// setButtonStatus.php
// Set button status as enable in session if not already set or if disabled
if(isset($_SESSION['setButtonStatus']) && $_SESSION['setButtonStatus'] == 'enable'){
    $_SESSION['setButtonStatus'] = 'disable';
} else {
    $_SESSION['setButtonStatus'] = 'enable';
}
?>

page1.php HTML代码

<input type="submit" name="submit" id="submit" value="<?php echo isset($_SESSION['setButtonStatus']) ? $_SESSION['setButtonStatus'] : 'enable' ; ?>" onclick="enable()"  >

page2.php HTML代码

<input type="submit" name="submit" id="submit" disabled="<?php echo isset($_SESSION['setButtonStatus']) && $_SESSION['setButtonStatus'] == 'disabled' ? true : false ; ?>" value="<?php echo isset($_SESSION['setButtonStatus']) ? $_SESSION['setButtonStatus'] : 'enable' ; ?>" onclick="enable()"  >

Answer 4

更改您的代码，如下所示 page1.php中

<html>
<head>
<script type="text/javascript">
function enable(){

var enable="enable";
alert(enable);
window.location = "page2.php?temp=" + enable;
}

</script>
</head>
<body>

单击按钮以进行删除或禁用

page2.php

<html>
<head>
</head>
<body>
<style>
#submit{
   display:none;
}
</style>
while page will load button is hide but if in url temp= enable then     buton will be visible
 <input type="button" value="button here" name="submit" id="submit"   <?php if($_GET['temp']=='enable'){ echo "style='display:block'";} ?>> 

 </body>
  </html>

enable second page button from first page
