使用javascript将用户类型转换为大写 [英] Convert to uppercase as user types using javascript

问题描述

我希望在用户使用javascript键入时将小写字母转换为大写字母。欢迎任何建议。

I want to convert lowercase chars to uppercase as the user types using javascript. Any suggestions are welcome.

我尝试过以下方法：

$("#textbox").live('keypress', function (e) {
    if (e.which >= 97 && e.which <= 122) {
        var newKey = e.which - 32;
        // I have tried setting those
        e.keyCode = newKey;
        e.charCode = newKey;
    }
});

推荐答案

$("#textbox").bind('keyup', function (e) {
    if (e.which >= 97 && e.which <= 122) {
        var newKey = e.which - 32;
        // I have tried setting those
        e.keyCode = newKey;
        e.charCode = newKey;
    }

    $("#textbox").val(($("#textbox").val()).toUpperCase());
});
