Lelee ike okwuntughe na Javascript ma ọ bụ jQuery na nkwupụta oge niile (site na ihe atụ nke akụkụ nkesa, kwa!)

Anọ m na-eme nyocha na ịchọta ezigbo ihe atụ nke onye nyocha Paswọdu na-eji JavaScript na Okwu mgbe nile (regex). N'ime ngwa n'ọrụ m, anyị na-eme post azụ iji nyochaa ike okwuntughe na ọ naghị adị mma maka ndị ọrụ anyị.

Gịnị bụ Regex?

Okwu mgbe niile bụ usoro mkpụrụedemede na-akọwa usoro ọchụchọ. Ọtụtụ mgbe, a na-eji usoro ndị dị otú ahụ eme ihe site na iji eriri ịchọ algorithms chọta or chọta ma dochie arụmọrụ na eriri, ma ọ bụ maka nkwado ndenye. 

O doro anya na isiokwu a agaghị akụziri gị okwu mgbe niile. Naanị ịmara na ikike iji Nkwupụta Okwu Oge niile ga-eme ka mmepe gị dị mfe ka ị na-achọ ụkpụrụ na ederede. Ọ dịkwa mkpa iburu n'uche na ọtụtụ asụsụ mmepe emeela ka kachasị mma iji okwu eme ihe… yabụ karịa ịkọwapụta na ịchọpụta eriri na-aga, Regex na-adịkarị ngwa ngwa ma sava na ndị ahịa.

Achọrọ m web ahụ ntakịrị oge tupu achọta m ihe atụ nke ụfọdụ nnukwu okwu oge niile na-achọ nchikota ogologo, mkpụrụedemede na akara. Agbanyeghị, koodu ahụ dị ntakịrị karịa maka uto m ma ahaziri maka .NET. Ya mere, m mere ka koodu ahụ dị mfe ma tinye ya na Javascript. Nke a na-eme ka ọ kwado ike paswọọdụ ozugbo na ihe nchọgharị onye ahịa tupu ikesa ya azụ… ma nye ụfọdụ nzaghachi nye onye ọrụ na ike paswọọdụ.

Na nke ọ bụla strok nke keyboard, paswọọdụ na-anwale megide mgbe okwu na mgbe ahụ nzaghachi na-nyere onye ọrụ na a na-adịru n'okpuru ya.

Ọrụ ike nke okwuntughe Javascript

The Okwu mgbe nile rụọ ọrụ dị egwu nke ibelata ogologo koodu ahụ. Ọrụ Javascript a na-enyocha ike okwuntughe yana ma imebi ya ọ dị mfe, ọkara, siri ike, ma ọ bụ nke siri ike ịkọ nkọ. Ka onye ahụ na-edepụta ihe, ọ na-egosiputa ndụmọdụ maka ịgba ya ume ka ọ dị ike. Ọ na-akwado paswọọdụ dabere na:

Ọrụ ahụ na-egosiputa ihe isi ike yana ụfọdụ ndụmọdụ maka imesi okwuntu ike n'ihu.

Ọrụ ike ike jQuery Paswọdu

Anyị nwekwara ike gbanwee agba nke ozi ma ọ bụrụ na-amasị anyị.

Harding Paswọdu gị arịrịọ

Ọ dị mkpa na ọ bụghị naanị igosipụta iwu okwuntughe n'ime Javascript gị. Nke a ga - enyere onye ọ bụla nwere ngwa mmepe ihe nchọgharị aka ka ọ gafee ederede ma jiri paswọọdụ ọ bụla masịrị ha. Kwesịrị ị na-eji ihe nkesa na-enyocha ihe iji kwado ike paswọọdụ tupu ịchekwa ya na ikpo okwu gị.

Ọrụ PHP maka ike okwuntughe

Ọrụ Python Maka Ike Paswọdu

Ọrụ C # Maka Ike Okwuntughe

Ọrụ Java Maka Ike Paswọdu
