如何防止iframe中的網頁在父頁執行回發時重新加載? 下面是一個簡單的.aspx頁面。當我單擊Button1時,會執行回發,將重新加載具有blank.aspx作爲其源的iframe。我怎樣才能防止這種情況發生?代碼如下。停止在回傳中重新加載iframe中的網頁
<div>
This is an empty page with a button to open a modal window in an iframe
<asp:Button ID="Button1" runat="server" Text="Postback" OnClick="Button1_Click" />
<asp:Label ID="lblPostback" runat="server" Text="Initial Load"></asp:Label>
<!-- Trigger/Open The Modal -->
<button id="myBtn" type="button">Open Modal</button>
<!-- The Modal -->
<div id="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<span class="close">×</span>
<p>Some text in the Modal..</p>
<iframe src="Site/Public/blank.aspx"></iframe>
</div>
</div>
<script>
// Get the modal
var modal = document.getElementById('myModal');
// Get the button that opens the modal
var btn = document.getElementById("myBtn");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];
// When the user clicks on the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
//When the user clicks anywhere outside of the modal, close it
window.onclick = function (event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
</script>
</div>
