摘要：需求最近在做微信小程序的時候，需要實(shí)現(xiàn)在搜索框的輸入內(nèi)容的時候?qū)崿F(xiàn)全局匹配實(shí)現(xiàn)高亮效果，目前的思路是，遞歸后臺來返回的數(shù)據(jù)，并將對象的值替換為需要的節(jié)點(diǎn)，并且通過來實(shí)現(xiàn)，高亮效果。

最近在做微信小程序的時候，需要實(shí)現(xiàn)在搜索框的輸入內(nèi)容的時候?qū)崿F(xiàn)全局匹配實(shí)現(xiàn)高亮效果，目前的思路是，遞歸后臺來返回的數(shù)據(jù)，并將對象的value值替換為需要的dom節(jié)點(diǎn)，并且通過rich-text來實(shí)現(xiàn)，高亮效果。

在實(shí)現(xiàn)的過程中主要考慮，不同類型的數(shù)據(jù)結(jié)構(gòu)，過濾掉特殊符號，url這些基本需求；同時在實(shí)現(xiàn)的過程中每次都要去處理最原始的數(shù)據(jù)，這就需要考慮到對象的深拷貝問題，目前所采用的方法是通過JSON.parse(JSON.stringify(str))來處理，因?yàn)樵谶@個全局搜索的項(xiàng)目中不太會用到函數(shù)這些對象。最后通過replace方法來處理這些目標(biāo)字符串。
