javascript - switch 语句不识别输入

Question

我有一个不重新识别输入的 switch 语句。它总是返回默认的...

如您所见，我onclick="rewrite("value")"在输入字段中添加了值。

我还有其他一些有效的 switch 语句，所以我真的在这里摸不着头脑......

由于我没有其他要添加的内容，因此我只是在此处添加文本，这样我就可以提交了。

欢迎任何帮助。

<div>
    <input type="image" value="sl" class="zastave" src="assets/drzave/Slo.png" onclick="rewrite('sl'); setInputs('sl');">
    <input type="image" value="en" class="zastave" src="assets/drzave/Ang.png" onclick="rewrite('en'); setInputs('en');">
    <input type="image" value="de" class="zastave" src="assets/drzave/Nem.png" onclick="rewrite('de'); setInputs('de');">
    <input type="image" value="it" class="zastave" src="assets/drzave/Ita.png" onclick="rewrite('it'); setInputs('it');">
    <input type="image" value="hr" class="zastave" src="assets/drzave/Hrv.png" onclick="rewrite('hr'); setInputs('hr');">
    <input type="image" value="ru" class="zastave" src="assets/drzave/Rus.png" onclick="rewrite('ru'); setInputs('ru');">
</div>

你从来没有定义你rewrite()的点击处理函数来接受输入参数。你应该这样做，然后switch在这个值上：

function rewrite(value) {
    // ...
    switch (value) {
        case "sl":
            advT.innerHTML = '';
            // etc.
            break;
