To check for case insensitive string contains, use the regular expressions. Add suffix “i” after the string regular expression as shown. var actualstring = "Javascript Regular Exp"; var regexp = "javascript"; /regexp/i.test(actualstring); //returns true ...
2. 内容过滤:在处理文本内容时,检测是否包含敏感词、非法字符或特定关键词,以进行内容审核、自动标记或过滤。 functioncontainsProfanity(text){constprofanities=["swearword1","swearword2","etc."];returnprofanities.some(word=>text.includes(word));}constmessage="This message contains a swearword!";console...
Use the localeCompare() String Method to Do Case Insensitive Comparison in JavaScriptWhile the method above gives an easy answer, it may not work well where the strings include Unicode characters. The localeCompare string method can take care of this. It is used with the sensitivity: 'base...
We look at the defaultArray.prototype.sortbehavior and discuss how you can do case insensitive string sorting. const foo =['Alpha','beta','Gamma','delta']; foo.sort((a, b)=>a.toLowerCase().localeCompare(b.toLowerCase())); foo.forEach(x=>console.log(x));/*"Alpha" "beta" "del...
# Ignoring case Check if Array contains String - Array.findIndex To do a case insensitive check if an array contains a string:Use the Array.findIndex() method to iterate over the array. Convert each array element and the string to lowercase and check for equality. If the condition is met...
