window.location.href not working
提问by Adam Zerner
My website is http://www.collegeanswerz.com/. I'm using rails. The code is for searching for colleges. I want the user to be able to type in the colleges name, click enter, and be taken to the url, rather than seeing the search results (if the user types in the name properly. if not I want to show the search results). I'm using "a" and "stackoverflow.com" as placeholders while I try to get it to work.
我的网站是http://www.collegeanswerz.com/。我正在使用导轨。该代码用于搜索大学。我希望用户能够输入大学名称，点击回车，然后被带到 url，而不是看到搜索结果（如果用户正确输入名称。如果没有，我想显示搜索结果） . 当我尝试让它工作时，我使用“a”和“stackoverflow.com”作为占位符。
I'm using window.location.href based on this: How to redirect to another webpage in JavaScript/jQuery?
我正在使用 window.location.href 基于这个：How to redirect to another web in JavaScript/jQuery?
javascript
javascript
$("#search_text").submit(function() {
if ($("#search_field").val() == "a")
{
window.location.href = "http://stackoverflow.com";
alert('worked');
}
});
layout file
布局文件
<%= form_tag("/search", :method => 'get', :id => 'search_text', :class => 'form_search') do -%>
<div id="search"> <%= search_field_tag :search, params[:search], :placeholder => 'enter college', :id => "search_field", :class => 'input-medium search-query' %></div>
<% end -%>
static_pages_controller.rb
static_pages_controller.rb
def search
@colleges = College.search(params[:search])
end
The alert is working, which tells me that the things inside the if statement should be being executed. But it's taking me to the normal search results instead of stackoverflow.com. Why is this?
警报正在运行，它告诉我应该执行 if 语句中的内容。但它把我带到了正常的搜索结果而不是 stackoverflow.com。为什么是这样？

The browser is still submitting the form after your code runs.
代码运行后，浏览器仍在提交表单。
Add return false;to the handler to prevent that.
添加return false;到处理程序以防止这种情况。

Try this
尝试这个
`var url = "http://stackoverflow.com";
$(location).attr('href',url);`
Or you can do something like this
或者你可以做这样的事情
// similar behavior as an HTTP redirect
window.location.replace("http://stackoverflow.com");
// similar behavior as clicking on a link
window.location.href = "http://stackoverflow.com";
and add a return false at the end of your function call
并在函数调用结束时添加 return false

请检查您使用的是//不是\\错误的，如下所示
Wrong:"http:\stackoverflow.com"
Right:"http://stackoverflow.com"
回答by Malek Tubaisaht
if anyone faced problem even after using return false;. then use the below.
如果有人在使用后遇到问题return false;。然后使用下面的。
setTimeout(function(){document.location.href = "index.php"},500);
