The XSP library contains classes that access the browser context.I have a simple php email form, but i am getting spam emails. Removes white space from both ends of a string. Gets the string representation of a String object.Ĭonverts all characters of a string to upper case. With, JavaScript does not care what data type (string or integer) you pass to it as long as the content that you provided it with matches. The result will always return either true or false. This means that you can perform logic tests to see if one thing is equal to another thing. Gets the string representation of a String object taking into account the host locale.Ĭonverts all characters of a string to upper case taking into account the host locale.Ĭonverts all characters of a string to lower case. In JavaScript, the operator is a comparison operator. Splits a string between string separators.Ĭhecks whether a string starts with a substring.Ĭhecks whether a string starts with a substring ignoring case.Ĭonverts all characters of a string to lower case taking into account the host locale. Using the default integer type in everyday situations means that integer constants and variables are immediately interoperable in your code and will match the. You can see an example of this when you compare the. Gets a substring starting and optionally ending at specified positions. While the modulo used with the int and float types will take the sign of the divisor, other types will not. Gets the index of the first occurrence of a substring. Removes white space from the right end of a string. Gets a substring starting at a specified position.Įxtends the object with additional properties and methods. Gets substrings that match a regular expression. Removes white space from the left end of a string. JavaScript programs may generate unexpected results if a programmer accidentally uses an assignment operator ( ), instead of a comparison operator ( ) in an if statement. Gets the index of the last occurrence of a substring ignoring case.Ĭompares two strings taking into account the host locale. Think of (negation operator) as 'not', (boolean-or operator) as 'or' and & (boolean-and operator) as 'and'. Gets the index of the last occurrence of a substring. If you see null (either assigned to a variable or returned by a function), then at that place should have been an object, but for some reason, an object wasn't created. Gets the index of a substring ignoring case.Ĭhecks whether a string is empty except for spaces. The JavaScript specification says about null: null is a primitive value that represents the intentional absence of any object value. Gets the character at a specified index as an integer code.Ĭhecks whether a string ends with a substring.Ĭhecks whether a string ends with a substring ignoring case.Ĭhecks whether a string equals another object or string.Ĭhecks whether a string equals another string ignoring case.Ĭhecks whether a string has a specified property. Represents common mathematical values and functions. The Standard library contains classes for manipulating data of different types and performing common operations. The Runtime library contains classes that provide useful methods for globalization. This library provides access to the IBM® Domino® back-end. Represents a document in XML Document Object Model format. Entering the name of a global object instantiates it. Global objects provide entry points to server-side scripts. Global objects and functions (JavaScript™).Note that some number literals, while looking like non. It will always return false if the value is not a number. The method will also return true for floating point numbers that can be represented as integer. If the value is NaN or Infinity, return false. Client-side scripts are interpreted by the browser.Ī simple action performs a pre-programmed activity that can be modified by arguments. If the target value is an integer, return true, otherwise return false. The JavaScript described here applies to the server-side interpreter. If both operands are null or both operands are undefined, return true. If both operands are objects, return true only if they refer to the same object. If the operands are of different types, return false. The JavaScript™ language elements are based on the ECMAScript Language Specification Standard ECMA-262 (see ). Description The strict equality operators ( and ) provide the IsStrictlyEqual semantic. JavaScript™ language elements (JavaScript).This reference describes the JavaScript™ language elements, Application Programming Interfaces (APIs), and other artifacts that you need to create scripts, plus the XPages simple actions. ![]()
