Simulate keypress without jquery
提问by Mateus Viccari
I have an input field, where the user can write things. I want that, if the user press the key "1", to simulate another key press "F". So, if the user typer the character 1, in the field it will display 1f. How can i do it, without using jQuery?
我有一个输入字段，用户可以在其中写东西。我希望，如果用户按下键“1”，模拟另一个键按下“F”。因此，如果用户键入字符 1，则在该字段中将显示 1f。我该怎么做，而不使用 jQuery？

var evt = document.createEvent("KeyboardEvent");
evt.initKeyEvent ("keypress", true, true, window,
0, 0, 0, 0,
13, 13);
var canceled = !body.dispatchEvent(evt);

For Webkit-based browser the initialization might be a bit different
对于基于 Webkit 的浏览器，初始化可能有点不同
initKeyboardEvent(in DOMString typeArg,
in boolean canBubbleArg,
in boolean cancelableArg,
in views::AbstractView viewArg,
in DOMString keyIdentifierArg,
in unsigned long keyLocationArg,
in boolean ctrlKeyArg,
in boolean shiftKeyArg,
in boolean altKeyArg,
in boolean metaKeyArg,
in boolean altGraphKeyArg);
