Common string methods in JS

Commonly used string methods in JS (recommended)

<SPAN style="FONT-FAMILY: &#39;courier new&#39;, courier">var str01 = "odd open xboxone" , str02 = "hey";
var str03;
var num = 15;　</SPAN>

// The first half of " str01. " is omitted below (this part is not this)

charAt(num) // Get the single character at the specified index position

charCodeAt(num) // Get the Unicode value of the character at the specified index position (ascii is its subset)

concat(str01,str02) //Concatenate two characters~

indexOf("str") //Get the index of the first occurrence of str

lastIndexOf( "str") // Get the index of the last occurrence of str

replace( "oldStr" , "newStr" ) // Find oldStr and replace it with newStr

slice( start, end) // The object can be a string or an array, remember that its range does not include end

substr( start, length) // Take length characters starting from the index start, and the length cannot be less than 0 otherwise returns an empty string

search("str") // Search for the string "str" ​​in str01 and return the index of its first character in str01

String.fromCharCode(uniNum,uniNum) //The parameter is a Unicode value (>=1 is enough)

str01.localeCompare(str02) //Compare based on local specific rules, if str01>str02 = 1, otherwise -1 is equal to 0
str03 = str02.valueOf(); // The original value of the string object (str02) can be returned

str03 = str01.split( "str") // Split the original string into an array object, the delimiter is a comma, and the parameter is an empty space string

var n = num.toString() // Change the Number object = >String object (n is a character), the source object has not changed

// The following is the basic style class

var txt = "heyguy"

txt.link("url") // Convert to hyperlink, remember to add http://

txt.big() // Can be changed to big/small/bold/italic/fixed/sub/sup/strike (strike is to delete the line)

txt. fontcolr("red") // name/rgb/#000000 is still the same old routine

txt.fontsize(num) //Only supports numbers
