js如果window.location.href不匹配,则跳转到

Question

如何做出window.location.href判断？

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

我的代码不起作用,或者我应该indexOf用来做裁判？谢谢.

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

有几件事:你错过了一个闭幕式,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';
} 

要么

// 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';
}
