Vue通过URL传参如何控制全局console.log的开关详解

const getQueryStr = (name) => {
 var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
 var r = window.location.search.substr(1).match(reg);
 if (r != null) return unescape(r[2]);
 return null;
};

console.log = function () {
 return false;
}

const getQueryStr = (name) => {
 var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
 var r = window.location.search.substr(1).match(reg);
 if (r != null) return unescape(r[2]);
 return null;
};
/* 若链接后面带上参数 envFlag=monitor
 * 则将 debug 置为true，否则置为false
*/
const monitor = 'monitor';
const envFlag = getQueryStr('envFlag');
let debug = monitor "%cNow You Can Console Log...", "color:red;font-size:18px;font-style:oblique;");
 debug = monitor;
} else {
 debug = '';
 console.log = function () {
 return false;
 }
}
const state = {debug: debug};
export const store = new vuex.Store({state, mutations});

<monitor v-show="debug"></monitor>
vuex: {
 getters: {
 debug: state => state.debug
 }
}
