如何将"disabled"按钮设置回"enabled"通过 PHP?



我有两个按钮,例如"保存"one_answers"创建"。现在我的问题是何时加载页面,"创建"按钮应"启用",并且"保存"按钮是"禁用"的。

现在,如果我单击"创建"按钮,则应"启用"保存"按钮,现在应该"禁用"启用"按钮。

//php code start
<?php
$isSaveDisabled = false;
if(isset($_POST['save']))
    {
        echo 'Hello robin';
        $isSaveDisabled = true;
    }
if(isset($_POST['create']))
    {
        echo 'Byeeee robin';
    }
?>
// php code ends
//bootstrap code start
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <link rel="stylesheet" href="BootStrap/css/bootstrap.min.css">
        <title></title>
    </head>
    <body >
        <div class="container jumbotron">
        <form action="" method="post">
            <div class="btn-group-xs">
            <button type="submit" id="btn1" name="save" <?php if ($isSaveDisabled) { echo 'disabled="disabled"';}?>>Save</button>
            <button type="submit" id="btn2" name="create">Create</button>
            </div>

        </form>
        </div>
    </body>
</html>
//bootstrap code ends

尝试..

//php code start
<?php
$isSaveDisabled = true;
$isCreateDisabled=false;
if(isset($_POST['save']))
    {
        echo 'Hello robin';
        $isCreateDisabled=false;
    }
if(isset($_POST['create']))
    {
        echo 'Byeeee robin';
        $isSaveDisabled = false;
    }
?>
// php code ends
//bootstrap code start
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <link rel="stylesheet" href="BootStrap/css/bootstrap.min.css">
        <title></title>
    </head>
    <body >
        <div class="container jumbotron">
        <form action="" method="post">
            <div class="btn-group-xs">
            <button type="submit" id="btn1" name="save" <?php echo $isSaveDisabled?'disabled':''; ?>>Save</button>
            <button type="submit" id="btn2" name="create" <?php echo $isCreateDisabled?'disabled':'';?>>Create</button>
            </div>

        </form>
        </div>
    </body>
</html>
//bootstrap code ends

可以使用jQuery完成。

尝试以下操作:

    $(document).on('click','#btn2',function(){
       $(this).prop('disabled',true);
       $('#btn1').prop('disabled',false);
    });

将其包括在您的html

<script>
 $(document).on('click','#btn2',function(){
       $("#btn2").prop('disabled',true);
       $("#btn1").prop('disabled',false);
    });
</script>

另外,在您中加入jQuery html。

使用A IF测试是否提交了页面与Create do disable create

<div class="btn-group-xs">
            <?php $create,$save = ''; if(isset($_POST['create'])) {$create = 'disabled';} else {$save = 'disabled';}?>
            <button type="submit" id="btn1" name="save" <?php $save?>>Save</button>
            <button type="submit" id="btn2" value="create" name="create" <?php $save?> >Create</button>
            </div>
