刷新页面后如何在单选按钮上保持选择 [英] How to keep selection on radio buttons after refreshing the page
问题描述
我有一个名为：radio_page.cshtml的View页面，它包含两个单选按钮。加载页面时，第一个单选按钮被默认选中。我需要点击第二个单选按钮刷新页面并保持选择第二个单选按钮，我正在尝试如下，但它不起作用。刷新页面后，选择将返回第一个单选按钮。请指教。谢谢。
//在视图中
@ Html.RadioButtonFor（m => m.Value，KW，new {style =width：70px，@ onClick =onRadioClick（this）;，@ check =checked}）KW
@ Html.RadioButtonFor（m => m.Value，HP ，new {style =width：70px，@ onClick =onRadioClick（this）;&}）HP
// JavaScript-In Javascript onradio按钮点击文本框将隐藏和显示。
< script type =text / javascript>
函数onRadioClick（e）
{
var SelectedValue = e.value;
if（SelectedValue ==" HP"）
{
document.getElementById（DvHP）。style.visibility =Visible;
document.getElementById（DvKW）。style.visibility =hidden;
}
else {
document.getElementById（DvHP）。style.visibility =hidden ;
文件。 getElementById（DvKW）。style.visibility =Visible;
}
}
< ; / script>
Hi,
I have a View page called: radio_page.cshtml, it contains two radio buttons. First radio button is checked as default when loading the page. I need when clicking on second radio button to refresh the page and keep selection on second radio button, I am trying that as below, but it does not work. After refreshing the page the selection returns to the first radio button. Please advise. Thanks.
//In View
@Html.RadioButtonFor(m=>m.Value, "KW", new { style = "width:70px", @onClick = "onRadioClick(this);", @checked = "checked" }) KW
@Html.RadioButtonFor(m=>m.Value, "HP", new { style = "width:70px", @onClick = "onRadioClick(this);&" })HP
//JavaScript-In Javascript onradio button click textboxes will be hide & show.
<script type="text/javascript">
function onRadioClick(e)
{
var SelectedValue = e.value;
if (SelectedValue == "HP")
{
document.getElementById("DvHP").style.visibility = "Visible";
document.getElementById("DvKW").style.visibility = "hidden";
}
else {
document.getElementById("DvHP").style.visibility = "hidden";
document.getElementById("DvKW").style.visibility = "Visible";
}
}
</script>
