Question

我有一个表单来向DB查询字符串提交值。我需要添加一个重置按钮以形成其余的清除表单并将结果恢复为默认值。

<form action="" method="post" id="report-page-form-form" class="clearfix">
    <?php
    $start_date = (isset($_POST['start-date']) ? 'value='.$_POST['start-date'] : 'placeholder="YYYY-MM-DD"');
    $end_date = (isset($_POST['end-date']) ? 'value='.$_POST['end-date'] : 'placeholder="YYYY-MM-DD"');
    ?>
    <div class="date-input-report clearfix">
        <label>Start Date:</label>
        <input type="text" name="start-date" <?php echo $start_date; ?> id="start"  readonly>
    </div>
    <div class="date-input-report clearfix">
        <label>End Date:</label>
        <input type="text" name="end-date"  id="end" <?php echo $end_date; ?> readonly>
    </div>
    <input class="form-submit" type="submit" value="Filter">
</form>

这是我的表格。任何人都可以帮我添加一个功能休息按钮。

You can do with Jquery:


$(".reset").bind("click", function() {
 $("input[type=text], textarea").val("");
});

使用此代码重置您的表单

    <form action="" method="post" id="report-page-form-form" class="clearfix">
<?php
$start_date = (isset($_POST['start-date']) ? 'value='.$_POST['start-date'] : 'placeholder="YYYY-MM-DD"');
$end_date = (isset($_POST['end-date']) ? 'value='.$_POST['end-date'] : 'placeholder="YYYY-MM-DD"');
?>
<div class="date-input-report clearfix">
<label>Start Date:</label>

<input type="text" name="start-date" <?php if(isset($_POST['reset'])) echo 'placeholder="YYYY-MM-DD"'; else echo $start_date; ?> id="start"  readonly>
</div>
<div class="date-input-report clearfix">
<label>End Date:</label>
<input type="text" name="end-date"  id="end" <?php if(isset($_POST['reset'])) echo 'placeholder="YYYY-MM-DD"'; else echo $end_date; ?> readonly>
</div>
<input class="form-submit" type="submit" value="Filter">
<input class="form-submit" type="submit" name="reset" value="Filter">

您可以使用Javascript：

document.getElementById("myForm").reset();

完成：

<form action="" method="post" id="report-page-form-form" class="clearfix">
    <?php
    $start_date = (isset($_POST['start-date']) ? 'value='.$_POST['start-date'] : 'placeholder="YYYY-MM-DD"');
    $end_date = (isset($_POST['end-date']) ? 'value='.$_POST['end-date'] : 'placeholder="YYYY-MM-DD"');
    ?>
    <div class="date-input-report clearfix">
        <label>Start Date:</label>
        <input type="text" name="start-date" <?php echo $start_date; ?> id="start"  readonly>
    </div>
    <div class="date-input-report clearfix">
        <label>End Date:</label>
        <input type="text" name="end-date"  id="end" <?php echo $end_date; ?> readonly>
    </div>
    <input class="form-submit" type="submit" value="Filter">
    <input type="button" onclick="clearForm()" value="clear form">
</form>

<script>
function clearForm() {
    document.getElementById("report-page-form-form").reset();
}
</script>

您可以使用输入类型重置按钮来实现此目的。

<form name="form" method="post">
   <input type="text" name="text1" placeholder="Name" action="" >
   <input type="submit" value="Submit" name="submit" />
   <input type="reset" name="reset" value="Reset Form" />
</form>
