フォーム自動入力して結果出力なんて処理を作るときに便利
function submitForm( value ){
var form = document.createElement( ‘form’ );
document.body.appendChild( form );
var input = document.createElement( ‘input’ );
input.setAttribute( ‘type’ , ‘hidden’ );
input.setAttribute( ‘name’ , ‘myvalue’ );
input.setAttribute( ‘value’ , value );
form.appendChild( input );
form.setAttribute( ‘action’ , ‘example.php’ );
form.setAttribute( ‘method’ , ‘post’ );
form.submit();
