window.location.href not working in Safari when using onkeypress
I'm using an asp textbox and a search button. In Safari if I click the search button i get redirected to the search results page using javascript window.location.href. But strangely the same javascript will not redirect to the page if I press return in the textbox.
Using the alert function I can see that window.location.href has the the correct url and the location bar at the top changes from the search page(default.aspx) to the search results url however when I click OK to the alert box the url at the top reverts back to the default.aspx page. It works on ie7/8/firefox/chrome but not safari. Here is my javascript,cs and aspx code:
function submitSearchOnEnter(e) {
var CodeForEnter = 13;
var codeEnteredByUser;
if (!e) var e = window.event;
if (e.keyCode开发者_运维技巧) codeEnteredByUser = e.keyCode;
else if (e.which) codeEnteredByUser = e.which;
if (codeEnteredByUser == CodeForEnter)
RedirectToSearchPage();
}
function RedirectToSearchPage() {
var searchText = $get('<%=txtHeaderSearch.ClientID%>').value
if (searchText.length) {
window.location.href = "Search.aspx?searchString=" + searchText;
}
}
protected void Page_Load(object sender, EventArgs e)
{
txtHeaderSearch.Attributes.Add("onkeypress", "submitSearchOnEnter(event)");
}
<asp:Panel ID="pnlSearch" runat="server" DefaultButton="lnkSearch">
<asp:TextBox ID="txtHeaderSearch" runat="server" CssClass="searchBox"></asp:TextBox>
<asp:LinkButton ID="lnkSearch" OnClientClick="RedirectToSearchPage(); return false;"
CausesValidation="false" runat="server" CssClass="searchButton">
SEARCH
</asp:LinkButton>
</asp:Panel>
I've tried return false; which doesn't allow me to enter any characters in the search box. I've spent ages online trying to find a solution. Maybe it has something to do with setTimeout or setTimeInterval but it didn't work unless i did it wrong.
In Safari, the 'onkeypress' event is only fired if the key press results in a character being added to an HTML element. I'm not sure that this will fire at all when you press Enter in a one-line text box. See a partial explanation of this behavior here.
As Tim Down says, you probably want onkeydown instead.
Use keydown instead of keypress and you should be fine.
protected void Page_Load(object sender, EventArgs e)
{
txtHeaderSearch.Attributes.Add("onkeydown", "submitSearchOnEnter(event)");
}
I had a similar issue.
It worked for me when using onKeyUp:
function bodyOnKeyUp(event)
{
if (!event) {event=window.event;}
var Esc = 27;
switch (event.keyCode) {
case Esc:
document.location.href='URL';
break;
}
}
<body onKeyUp="bodyOnKeyUp(event)">
...
</body>
加载中,请稍侯......
