Info

Javascript Ex: document.close( ) open( ) 3 Deletes existing document content and opens a stream to which new document contents may be written. Returns nothing. Ex: document.open( ) write( value, ...) 4 Inserts the specified string or strings into the document currently being parsed or appends to document opened with open( ). Returns nothing. Ex: document.write( value, ...) writeln( value, ...) 5 Identical to write( ), except that it appends a newline character to the output. Returns nothing. Ex: document.writeln( value, ...) Example We can locate any HTML element within any HTML document using HTML DOM. For instance, if a web document contains a form element, then using JavaScript, we can refer to it as document.forms[0]. If your Web document includes two form elements, the first form is referred to as document.forms[0] and the second as document.forms[1]. Using the hierarchy and properties given above, we can access the first form element using document.forms[0].elements[0] and so on. Here is an example to access document properties using Legacy DOM method. Document Title
Javascript { var ret = document.title; alert("Document Title : " + ret ); var ret = document.URL; alert("Document URL : " + ret ); var ret = document.forms[0]; alert("Document First Form : " + ret ); var ret = document.forms[0].elements[1]; alert("Second element : " + ret ); } //--> This is main title Click the following to see the result: Output 331
