Answer 1

如果我理解你的问题是正确的，你想将$ Id变量传递给你的函数吗？

onclick=\"javascript:toggleSound($id);\"

<script type=\"text/javascript\">

<script type=\"text/javascript\">


 function toggleSound(inVar) {
    //inVar is equal to the variable you want to pass into the function.

        audioElem = document.getElementById(inVar);
        if (audioElem.paused)
            audioElem.play();
        else
            audioElem.pause();
    }
</script>
