之前用代码：
if (pageType === ROUTER_PAGE.NONE){ for (let eachPageKey of Object.keys(ROUTER_PAGE)){ console.log("——–"); const eachPage = ROUTER_PAGE[eachPageKey]; const toCompareUrl = `${ENV_PREFIX}${eachPage.urlPattern}`; console.log(`currentUrl=${currentUrl},toCompareUrl=${toCompareUrl}`); const matched = currentUrl.match(toCompareUrl); console.log(`matched=${matched}`); if (matched !== null) { console.log(`Found match matched=${matched}`); pageType = eachPage; break; } } } |
结果：
currentUrl=/breedingAdd/0,toCompareUrl=/ index.js?5c2a:335 matched=/ index.js?5c2a:338 Found match matched=/ |
即：
对于：
当前url来说：
/breedingAdd/0
去匹配
/
结果竟然是可以匹配到的：
/
不是以为：
匹配不到，返回null
所以要去找js中的字符串的正则匹配

【总结】
后来就不继续折腾复杂的正则匹配了。
暂时使用startsWith吧：
// 2. if above not same url, then try match prefix // and exclue the NONE and MAIN(its url pattern is /) if (pageType === ROUTER_PAGE.NONE){ for (let eachPageKey of Object.keys(ROUTER_PAGE)){ console.log("——–"); const eachPage = ROUTER_PAGE[eachPageKey]; if ((eachPage === ROUTER_PAGE.NONE) || (eachPage === ROUTER_PAGE.MAIN)) { continue; } const toCompareUrl = `${ENV_PREFIX}${eachPage.urlPattern}`; //const matched = currentUrl.match(toComparePattern); const matched = currentUrl.startsWith(toCompareUrl); console.log(`toCompareUrl=${toCompareUrl}, currentUrl=${currentUrl} -> matched=${matched}`); // const toComparePattern = `/^${toCompareUrl}/ig`; // console.log(`toComparePattern=${toComparePattern}`); // const isMatch = toComparePattern.test(currentUrl); // console.log(`toCompareUrl=${toCompareUrl},toComparePattern=${toComparePattern}, currentUrl=${currentUrl} -> isMatch=${isMatch}`); // if (isMatch) { // if (matched !== null) { if (matched) { pageType = eachPage; break; } } } |
然后去匹配：
toCompareUrl=/breedingProcess, currentUrl=/breedingAdd/0 -> matched=false index.js?5c2a:333 ——– index.js?5c2a:344 toCompareUrl=/breedingAdd, currentUrl=/breedingAdd/0 -> matched=true index.js?5c2a:362 parsePageType: currentUrl=/breedingAdd/0 -> page=新增配种 |
