如何进行window.location.href判断？

如果window.location.href不匹配?search=，则使当前url跳转到http://localhost/search?search=car

我的代码不起作用，或者我应该使用 indexOf 来进行判断？谢谢。

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

有几件事：你缺少一个右括号，并且你需要转义 ?因为它对于正则表达式很重要。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';
}

或者

// 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';
}

A couple of things: you're missing a closing paren, and you need to escape the ? because it's significant to regular expressions. Use either /\?search=/ or '\\?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';
}

// 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';
}
