我是新手,试图弄明白。非常感谢你看看!
这有效:当用户选择'include'radio时,在表单(index.html)上,内容会显示在表单上,然后在welcome.php上提交。除此之外它是隐藏的。
问题:如果没有在字段'animalvillas1','animalvillas2'和&中输入任何内容,我也希望这样做并隐藏在welcome.php上显示的内容。 'animalvillas3'独立。
请参阅index.html& welcome.php如下:
的index.html
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
$(function () {
$("input[name='animalvillas']").click(function () {
if ($("#chkYes1").is(":checked")) {
$("#dvanimalvillas").show();
} else {
$("#dvanimalvillas").hide();
}
});
});
</script>
</head>
<form name="create" action="welcome.php" method="post">
<span><strong>Lodge Villas - Jambo</strong></span><BR />
<label for="chkYes1">
<input type="radio" id="chkYes1" name="animalvillas" value="Y" />
Include
</label>
<label for="chkNo1">
<input type="radio" id="chkNo1" name="animalvillas" value="N" checked />
Exclude
</label>
<hr />
<div id="dvanimalvillas" style="display: none">
$<input type="text" name="animalvillas1" size="3" /> - Value Studio - Standard View (Parking View) <br>
$<input type="text" name="animalvillas2" size="3" /> - Deluxe Studio - Standard View (Water / Pool) <br>
$<input type="text" name="animalvillas3" size="3" /> - Deluxe Studio - Savanna View <br>
</div>
<input type="submit" />
</form>
的welcome.php
<div id="dvanimalvillas" <?php echo ($_POST['animalvillas'] == "N") ? 'style="display:none;"' : '' ; ?>>
<?php
$animalvillas1 = $_POST["animalvilas1"];
$animalvillas2 = $_POST["animalvilas2"];
$animalvillas3 = $_POST["animalvilas3"];
if(!empty($animalvillas1)){
echo "$".$_POST["animalvilas1"]." - Value Studio - Standard View <BR>";
}
if(!empty($animalvillas2)){
echo "$".$_POST["animalvilas2"]." - Deluxe Studio - Standard View <BR>";
}
if(!empty($animalvillas3)){
echo "$".$_POST["animalvilas3"]." - Deluxe Studio - Savanna View <BR>";
}
?>
</div>
答案 0 :(得分:1)
在welcome.php
中,您可以添加以下内容:
$hide = $_POST['animalvillas'] === "N" || (
empty($_POST["animalvilas1"])
&& empty($_POST["animalvilas2"])
&& empty($_POST["animalvilas3"]));
<div id="dvanimalvillas" <?php echo $hide ? 'style="display:none;"' : '' ; ?>>
<?php .... ?>
</div>
如果$_POST['animalvillas'] === "N"
或所有输入都为空,这将隐藏内容!
我希望这会有所帮助。
