正則表達式不匹配 - Javascript

Question

我在查詢wiktionary API，並且需要匹配「===名詞===」，包括之後的文本，直到「==== Translations ====」開始。實際的JSON對象比較大，我需要匹配幾次，包括「===動詞===」等。在Regexr.com上，我設法讓它匹配，但不是在我的JavaScript：

var regex = /(===Verb===|===Noun===|===Adjective===|===Adverb===).*?====/g; 
    console.log(jsondata.match(regex)); 
    console.log(regex.test(jsondata)); 

任何幫助非常感謝！

Answer 1

確保你的json被正確地轉義了。

在我的例子，我躲過了話ōʹvə-flō'，ō'və-flōʹ，ōʹvər-flō'和ō'vər-flōʹ到ōʹvə-flō\'，ō\'və-flōʹ，ōʹvər-flō\'和ō\'vər-flōʹ，分別工作：

var json = '<root><h level="2" i="1">==English==</h> <template lineStart="1"><title>wikipedia</title><part><name>dab</name>=<value>overflow</value></part><part><name>lang</name>=<value>en</value></part></template> <h level="3" i="2">===Etymology===</h> From <template><title>prefix</title><part><name index="1"/><value>over</value></part><part><name index="2"/><value>flow</value></part><part><name>lang</name>=<value>en</value></part></template>. Literally corresponds to <template><title>term</title><part><name index="1"/><value>superfluous</value></part><part><name>lang</name>=<value>en</value></part></template>, which is from Latin, rather than Germanic. <h level="3" i="3">===Pronunciation===</h> * <template><title>a</title><part><name index="1"/><value>RP</value></part></template> ** <template><title>sense</title><part><name index="1"/><value>noun</value></part></template> <template><title>enPR</title><part><name index="1"/><value>ōʹvə-flō\'</value></part></template>, <template><title>IPA</title><part><name index="1"/><value>/ˈəʊvəˌfləʊ/</value></part><part><name>lang</name>=<value>en</value></part></template> ** <template><title>sense</title><part><name index="1"/><value>verb</value></part></template> <template><title>enPR</title><part><name index="1"/><value>ō\'və-flōʹ</value></part></template>, <template><title>IPA</title><part><name index="1"/><value>/ˌəʊvəˈfləʊ/</value></part><part><name>lang</name>=<value>en</value></part></template> * <template><title>a</title><part><name index="1"/><value>GenAm</value></part></template> ** <template><title>sense</title><part><name index="1"/><value>noun</value></part></template> <template><title>enPR</title><part><name index="1"/><value>ōʹvər-flō\'</value></part></template>, <template><title>IPA</title><part><name index="1"/><value>/ˈoʊvɚˌfloʊ/</value></part><part><name>lang</name>=<value>en</value></part></template> ** <template><title>sense</title><part><name index="1"/><value>verb</value></part></template> <template><title>enPR</title><part><name index="1"/><value>ō\'vər-flōʹ</value></part></template>, <template><title>IPA</title><part><name index="1"/><value>/ˌoʊvɚˈfloʊ/</value></part><part><name>lang</name>=<value>en</value></part></template> * <template><title>rhymes</title><part><name index="1"/><value>əʊ</value></part><part><name>lang</name>=<value>en</value></part></template> <h level="3" i="4">===Noun===</h> <template lineStart="1"><title>en-noun</title></template> # The [[spillage]] resultant from overflow; [[excess]]. # [[outlet|Outlet]] for escape of excess material. # <template><title>context</title><part><name index="1"/><value>computing</value></part><part><name>lang</name>=<value>en</value></part></template> The situation where a value exceeds the available [[numeric]] [[range]]. <h level="4" i="5">====Translations====</h> <template lineStart="1"><title>trans-top</title><part><name index="1"/><value>spillage</value>'; 
 

 
var regex = new RegExp(/(===Verb===|===Noun===|===Adjective===|===Adverb===).*?====/g); 
 

 
document.write(json.match(regex));

Answer 2

你沒有捕捉串的正確部分

/(?:===Verb===|===Noun===|===Adjective===|===Adverb===)(.*?)====Translations====/g

Answer 3

似乎在這個小提琴，替你的正則表達式

var regex = /(===Verb===|===Noun===|===Adjective===|===Adverb===).*?====/g;
