[英]Close a div by clicking a button inside the div
I want to close the main div by clicking close button which is inside that div. 我想通过单击该div内的关闭按钮来关闭主div。 What JavaScript code do I need to write in iframe to achieve it?
为此,我需要在iframe中编写哪些JavaScript代码?
Main Page :- 主页 :-
<html>
<head>
<script type="text/javascript">
function showhide()
{
var div = document.getElementById("newpost");
if (div.style.display !== "none") {
div.style.display = "none";
}
else {
div.style.display = "block";
}
}
</script>
<style>
#newpost {
z-index: 1;
display:none;
background-color: rgba(255,255,255,0.9);
position:fixed;
width:100%;
height:100%;
overflow:auto;
}
#myframe {
z-index: 2;
position:fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
</style>
</head>
<body>
<div class="newpost" id="newpost">
<div class="myframe" id="myframe"><iframe id="signup_frame1" width="750" height="420" src="iframe.html" frameborder="0" allowfullscreen></iframe></div>
</div>
<FONT COLOR="#696969" onclick="showhide()"><span style="cursor:pointer">Show div</span></font>
</body>
</html>
iframe.html :- iframe.html:-
<html>
<head>
<script type="text/javascript">
function showhide()
{
var div = document.getElementById("newpost");
if (div.style.display !== "none") {
div.style.display = "none";
}
else {
div.style.display = "block";
}
}
</script>
</head>
<body>
<FONT COLOR="#696969" onclick="showhide()"><span style="cursor:pointer">Close div</span></font>
</body>
</html>
Since your iFrame is on the same domain there is a way to do this. 由于您的iFrame位于同一域中,因此有一种方法可以做到这一点。 For example,
例如,
<div id="close">
<iframe src="/HTMLPage2.htm">
</iframe>
</div>
Then inside the iFrame something like this should do the trick: 然后在iFrame中执行以下操作:
<script>
function closeDiv() {
window.parent.document.getElementById("close").style.display = "none";
}
</script>
<input value="close div" type="button" onclick="closeDiv()"/>
Specific to the code that is inside your iFRAME, it needs to be this instead: 特定于您iFRAME内的代码,它需要改为:
function showhide() {
var div = window.parent.document.getElementById("newpost");
if (div.style.display !== "none") {
div.style.display = "none";
}
else {
div.style.display = "block";
}
}
All said and done, your code should be this: 说完了,您的代码应该是这样的:
Main page - 主页 -
<html>
<head>
<script type="text/javascript">
function showhide() {
var div = document.getElementById("newpost");
if (div.style.display !== "none") {
div.style.display = "none";
}
else {
div.style.display = "block";
}
}
</script>
<style>
#newpost
{
z-index: 1;
background-color: rgba(255,255,255,0.9);
position: fixed;
width: 100%;
height: 100%;
overflow: auto;
}
#myframe
{
z-index: 2;
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
</style>
</head>
<body>
<div class="newpost" id="newpost">
<div class="myframe" id="myframe">
<iframe id="signup_frame1" width="750" height="420" src="/iframe.htm" frameborder="0" allowfullscreen></iframe>
</div>
</div>
<font color="#696969" onclick="showhide()"><span style="cursor: pointer">Show div</span></font>
</body>
</html>
iframe - iframe-
<html>
<head>
<script type="text/javascript">
function showhide() {
var div = window.parent.document.getElementById("newpost");
if (div.style.display !== "none") {
div.style.display = "none";
}
else {
div.style.display = "block";
}
}
</script>
</head>
<body>
<FONT COLOR="#696969" onclick="showhide()"><span style="cursor:pointer">Close div</span></font>
</body>
</html>
If you can use jQuery: 如果可以使用jQuery:
$('#signup_frame1').load(function(){
var iframe = $('#signup_frame1').contents();
iframe.find("#Close_btn_ID").click(function(){
$("#myframe").hide();
});
});
Here, "#Closebtn_ID" will be the ID of the Button inside iFrame where you want to attach the click handler. 在这里, “#Closebtn_ID”将是您要在其中附加点击处理程序的iFrame中按钮的ID。
