js如果window.location.href不匹配，则跳转到

Question

如何判断window.location.href？

如果window.location.href与?search=不匹配，请将当前网址跳至http://localhost/search?search=car

我的代码不起作用，或者我应该使用indexOf来判断？感谢。

if(!window.location.href.match('?search='){
    window.location.href = 'http://localhost/search?search=car';
}

有几件事：你错过了一个关闭的人，你需要逃避？因为它对正则表达式很重要。使用/ \？search = /或'\？search ='。

// Create a regular expression with a string, so the backslash needs to be
// escaped as well.
if (!window.location.href.match('\\?search=')) {
    window.location.href = 'http://localhost/search?search=car';
} 

或

// Create a regular expression with the /.../ construct, so the backslash
// does not need to be escaped.
if (!window.location.href.match(/\?search=/)) {
    window.location.href = 'http://localhost/search?search=car';
}
