To make the timer work cyclically, you need to write a function to implement cyclic calling. Here is an example: VaR the_count = 0;VaR the_timeout;Function dotimer (){Optional parameter Doc ument. timer_form.the_text.value = the_count;The_count + = 2;The_timeout = setTimeout ("dotimer ();", 2000 );} The timer used here is the timer used for the previous page. This function is called when you click the button. This function writes the current value

A table can contain at most one matching record, which is read from the beginning of the query. Since there is only one record, the field values recorded by this row in the remaining optimization programs can be treated as a constant value. The const table query is very fast, because only one read is required! Const is used to compare a fixed value with a primary key or UNIQUE index. In the following queries, tbl_name is the const table:SELECT * FROM tbl_name WHERE primary_key =

1. Conversion between objects and basic types:No matter when the object is not null, it is true in a Boolean environment.For example;New Boolean (false );New Number (0 );New String ("");New Array ();Although the internal value is false, the object value is true;Object? ValueOf ()? ToString ()In the Date class, toString () conversion is performed first.2. operate a data value in js:Methods for operating data

by developers when writing an unfinished test method, marking that a test method has not been completed yet, similarly, the test result is not fail, but the phpunit test method has not been completed. The example is as follows: Php Public Function TestAreNotEnoughHours (){ $ This -> MarkTestIncomplete ( " There aren't enough hours in the day to have my tests go green " ); $ TrueVariable = True ; $ This -> AssertTrue ( $ TrueVariable );} ?> 2.

Javascript: First JavaScript Basics 1. Javascript character set:Javascript uses the Unicode Character Set encoding.Why is this encoding used?The reason is simple. The 16-bit Unicode code can represent any written language of the Earth. This is an important feature of language internationalization. (You may have seen writing scripts in Chinese, such as: function my function (){});Each character in Javascript is expressed in two bytes. (Because it i
