Various javascript implementation test rules _ javascript skills

This article mainly introduces various javascript verification rules, involving javascript Detection Techniques for mobile phone numbers, email addresses, URLs, Chinese characters, and images, which are of reference value, for more information about how to implement javascript verification, see the following examples. Share it with you for your reference. The details are as follows:

/*** Check various rules ** @ param str check content * @ param cType pre-configured check rule string [* empty, check whether it is blank * telphone, landline phone number * allphone, all mobile phone numbers * ydphone, mobile phone number * ltphone, Unicom mobile phone number * dxphone, Telecom Mobile Phone Number * email, email * url, url * cn, Chinese character * image, the image format is * emscode, zip code * isEmpty. check whether it is empty * isint, integer * isfloat, whether it is a positive decimal * isnumber, and whether it is a real number * words, determine whether it is an English letter * wordsAndNum, whether it is a letter + number * wordsAndNumAndDownline, and whether it is a string * qq consisting of digits, 26 English letters, or underscores, QQ test * personCard18, ID card 18 digits * personCard15, ID card 15 digits *] * @ param regex custom expression input format for example: "^ \-? [1-9] + \ d * $ "** @ description cType and regex can only be empty. * For example, checkObjectByRegex (" test Chinese "," cn "); // judge Chinese characters * such as checkObjectByRegex ("test Chinese", null, "^ [\ u4e00-\ u9fa5] + $ "); // custom expression regular * @ return {boolean} */function checkObjectByRegex (str, cType, regex) {/*** defines the regular expression object for verifying various formats */var Regexs = {telphone: (/^ (\ d {3 }\)) | (\ d {3 }\-))?
