Text.onchange() Handler


Text.onchange() Handler---invoked when input value changes


Navigator 2.0, Internet Explorer 3.0


       onchange="handler-statements" ...>  a definition of the handler
text.onchange a reference to the handler
text.onchange();  an explicit invocation of the handler


The Text.onchange() event handler is defined by the onChange attribute of the <INPUT> HTML tag that defines the Text object. The value of this attribute may be any number of JavaScript statements, separated by semicolons; these statements will be executed whenever the user changes the value in the input field and then "commits" those changes by moving keyboard focus elsewhere (i.e., by clicking the mouse elsewhere or by typing the Tab or Return keys). This handler is intended to process a complete change to the input value, and therefore is not invoked on a keystroke-by-keystroke basis. Also, note that the onchange() event hander is not invoked when the value property of a Text object is set by JavaScript.
