At this time, we need to write different CSS for different browsers, so that it can be compatible with different browsers, can also be in different browsers to get the desired page effect. The process of writing different CSS code for different browsers is called C

The eval () function is required here, as shown below:Copy codeThe Code is as follows: var str = "abc"; // This may be a dynamic variable.Var patt1 = eval ("// \ [" + str + "\]/"); // equivalent to var patt1 =/\ [abc \]/;Alert ("[abc]". match (patt1); // return [abc] B.

instantiated and the form is visible.The load is thrown, the form is present, but not visible. The form does not yet exist during the execution of the constructor.If the Visible property is set to true in the constructor or the show method is called. The Load event is immediately raised, which also makes the form visible.When the form is closed, the closing event occurs when it is shutting down, and the Cancel property is set to True to cancel the shutdownClosed occurs after the form is closed.

the number is turned out, if there are characters, turn out Nan. If it is empty, turn out 0.The Parsenint () function has the following transformations: see if the first character is a number to decide whether to go out. For the problem of the binary, provide the second parameter is the binary number.The Parsenfloat () function has the following transformations: It only applies to decimal when it is converted, so the hexadecimal data is turned out 0.3) The length of any one string can be output

functions in other languages: You do not need to specify a function's return value, because any ECMAScript function can return any value at any time. In fact, a function that does not specify a return value returns a special undefined value. There is also no concept of a function signature in ECMAScript, because its function parameters are passed in a form of an array of 0 or more values. You can pass any number of arguments to the ECMAScript function, and you can access th

can be a variable, or even an expression. The switch statement uses the strict equality operator when comparing values, so type conversions do not occur. Any function can implement the return value at any time by the return statement followed by the value to be returned, and any code after the return statement will never be executed. Strict mode has some limitations on functions: The function cannot be named eval or arguments;The parameter cannot be named eval or arguments;Two name

The difference is that encodeURI () does not encode special characters that are themselves URIs, such as colons, forward slashes, question marks, and well sizes, while encodeuricomponent () encodes any non-standard characters it discovers.

This chapter mainly introduces some of the history of JavaScript:1.Javascript mainly consists of three parts: Ecmascript,dom,bom.ECMAScript: The mainstream browser is now fully supported.DOM: Maps the entire HTML page to a multi-tiered node structure. With the API provided by the DOM, developers can easily delete, add, replace, or modify nodes.BOM: Control browser window size, move, Ajax object, etc.Summary: JavaScript is a scripting language specifically designed to interact with Web pages."Ava
