我有一个link
到form
的网页。点击link
form
显示后,link
消失。我遇到的问题是,当我点击浏览器的back button
时,URL的值会发生变化,但页面的状态不会恢复到以前的状态。 form
应该消失,link
显示回来。同样在form
可见时重新加载,页面将返回其第一个状态,我需要阻止其发生。
代码:
<html>
<style>
.titimmo {
text-align: center;
padding: 10px;
font-size: 14pt;
background-color: #CC3300;
display: block;
}
.hidden {
display: none;
}
.visible {
display: block;
}
#formContainer {
padding: 1em 0 1em 2em;
background-color: #E8E8E8;
margin: 1em 0 1em 2em;
width: 88.9%;
}
#formContainer h4 {
color: #FF3300;
}
</style>
<body>
<div id="categContainer1">
<div class="titimmo"><a href="add.php?c=realestate" id="a_categ">Real Estate</a></div>
</div>
<div id="formContainer" class="hidden">
<form action="add.php" method="post">
<h4>Location :</h4>
<input type="text" name="made"/>
<h4>Price :</h4>
<input type="text" name="modele"/><br/><br/>
</form>
</div>
<script>
function stepone() {
document.getElementById('a_categ').onclick = function () {
document.getElementById('categContainer1').className += " hidden";
document.getElementById('formContainer').className = "visible";
window.history.pushState('Form', 'My form', this.getAttribute("href"));
return false
};
}
stepone();
</script>
</body>
</html>

要使其发挥作用,您需要做两件事:
这是一个基本的例子:
var formVisible = localStorage.formVisible || false;
var cContainer = document.getElementById('categContainer1');
var fContainer = document.getElementById('formContainer');
function formOpen(e) {
cContainer.className = "hidden";
fContainer.className = "visible";
window.history.pushState('Form', 'My form', this.getAttribute("href"));
localStorage.formVisible = 'Y';
return false;
};
function formClose(e) {
cContainer.className = "visible";
fContainer.className = "hidden";
localStorage.removeItem( 'formVisible' );
};
if( formVisible ) formOpen();
document.getElementById('a_categ').onclick = formOpen;
window.onpopstate = formClose;
var formVisible = localStorage.formVisible || false;
var cContainer = document.getElementById('categContainer1');
var fContainer = document.getElementById('formContainer');
function formOpen(e) {
cContainer.className = "hidden";
fContainer.className = "visible";
window.history.pushState('Form', 'My form', this.getAttribute("href"));
localStorage.formVisible = 'Y';
return false;
};
function formClose(e) {
cContainer.className = "visible";
fContainer.className = "hidden";
localStorage.removeItem( 'formVisible' );
};
if( formVisible ) formOpen();
document.getElementById('a_categ').onclick = formOpen;
window.onpopstate = formClose;

}

}
.visible {

}
#formContainer {

<div id="categContainer1">
<div class="titimmo">

</div>
</div>
<div id="formContainer" class="hidden">
<form action="add.php" method="post">
<h4>Location :</h4>
<input type="text" name="made" />
<h4>Price :</h4>

同样在Fiddle,您可以看到它的工作原理。
