从下拉列表中打开模式以添加客户端 [英] Opening modal from dropdown list to add client
问题描述
昨天链接到我以前的文章,内容涉及如何使选择器的值更改我的javascript的行为,我在打开模式窗口时遇到了麻烦.
Linked to my prior post yesterday on how to have a value of a selector change the behaviour of my javascript, I run into trouble opening a modal window.
这个想法是,如果从第一个下拉列表中选择添加客户端",而不是用项目"动态填充第二个下拉列表,则会弹出一个模式窗口,以允许用户添加客户端.
The idea is that if "add client" is selected from the first dropdown list, instead of dynamically populating the second dropdown list with "projects", a modal window pops-up to allow the user to add a client.
我有index3.php:
I have index3.php:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
include 'dbconnect.php';
?>
<script type="text/javascript" src="scripts/jquery-3.1.1.min.js"></script>
<script type="text/javascript">
function fetch_select(val)
{
if (val != "add_client")
{
$.ajax({
type: 'post',
url: 'fetch_data.php',
data: {
get_option:val
},
success: function (response) {
document.getElementById("projects").innerHTML=response;
}
});
}
else
{
//code to open modal below
success: function overlay() {
el = document.getElementById("overlay");
el.style.visibility = (el.style.visibility == "visible") ? "hidden" : "visible";
}
//code to open modal above
}
}
</script>
<?php
echo "<table>";
echo "<form action='index3.php method='post'>";
echo "<tr>";
echo "<td>";
echo "<select name='client' id='client' onchange='fetch_select(this.value);'>";
echo "<option>Name of Firm</option>";
$select = mysqli_query($Verbinding,"SELECT client FROM clients GROUP by client");
while ($row = mysqli_fetch_array($select))
{
echo '<option value="'.$row['client'].'">'.$row['client'].'</option>';
}
echo "<option value='add_client'>Add Client</option>";
echo "</select>";
echo "</td>";
echo "<td>";
echo "<select name='project' id='projects'>";
echo "<option>Select Project</option>";
echo "</select>";
echo "</td>";
echo "</tr>";
echo "</table>";
echo "</form>";
echo "<div id='overlay'>";
echo "<div>";
echo "<p>Content of modal window.</p>";
echo "</div>";
echo "</div>";
?>
样式表modal.css可以工作,并且通过dbconnect.php包含在内,并且包含:
The stylesheet modal.css works and is included through dbconnect.php and contains:
modal.css
modal.css
#overlay {
visibility: hidden;
position: absolute;
left: 0px;
top: 0px;
width:100%;
height:100%;
text-align:center;
z-index: 1000;
}
#overlay div {
width:300px;
margin: 100px auto;
background-color: #fff;
border:1px solid #000;
padding:15px;
text-align:center;
}
希望任何人都能提供帮助,谢谢保罗,并致以亲切的问候
Hope anyone can help, thanks and with kind regards, Paul
推荐答案
success: function overlay() {
el = document.getElementById("overlay");
el.style.visibility = (el.style.visibility == "visible") ? "hidden" : "visible";
}
什么也没做.您已经将ajax调用的成功"回调(定义了一个选项,其中包含稍后运行的功能)与常规的日常代码混淆了.
is not doing anything. You've confused the "success" callback of the ajax call (which defines an option, containing a function to run later) with regular everyday code.
假设模态的ID定义为覆盖",则可以执行以下操作:
Assuming your modal has its id defined as "overlay", then you can just do:
else
{
//code to open modal below
el = document.getElementById("overlay");
el.style.visibility = (el.style.visibility == "visible") ? "hidden" : "visible";
//code to open modal above
}
