将 javascript 函数解析为两个不同的按钮 onclick

Question

大家好，我将下面的函数分成了两个单独的函数。这些功能不起作用，但我没有收到任何错误消息？主要功能：

function sipToggleMute() {
            if (oSipSessionCall) {
                var i_ret;
                var bMute = !oSipSessionCall.bMute;
                txtCallStatus.innerHTML = bMute ? '<i>Mute the call...</i>' : '<i>Unmute the call...</i>';
                i_ret = oSipSessionCall.mute('audio'/*could be 'video'*/, bMute);
                if (i_ret != 0) {
                    txtCallStatus.innerHTML = '<i>Mute / Unmute failed</i>';
                    return;
                }
                oSipSessionCall.bMute = bMute;
                btnMute.value = bMute ? "Unmute" : "Mute";
            }
        }

解析函数：

function sipMute() {
if (oSipSessionCall) {
    var i_ret;
    var bMute = !oSipSessionCall.bMute;
    txtCallStatus.innerHTML = '<i>Mute the call...</i>';
    i_ret = oSipSessionCall.mute('audio'/*could be 'video'*/, bMute);
    if (i_ret != 0) {
        txtCallStatus.innerHTML = '<i>Mute failed</i>';
        return;
    }
    oSipSessionCall.bMute = "Unmute";
}

}

function sipunMute() {
    if (oSipSessionCall) {
        var i_ret;
        var bMute = !oSipSessionCall.bMute;
        txtCallStatus.innerHTML =  '<i>Unmute the call...</i>';
        i_ret = oSipSessionCall.mute('audio', bMute);
        if (i_ret != 0) {
            txtCallStatus.innerHTML = '<i> Unmute failed</i>';
            return;
        }
        oSipSessionCall.bMute = "Mute";
    }

您的两个函数都在切换当前状态，原因是：

var bMute = !oSipSessionCall.bMute;

一个函数应设置为true，另一个应设置为false

function sipMute() {
    if (oSipSessionCall) {
        var i_ret;
        var bMute = true;
        txtCallStatus.innerHTML = '<i>Mute the call...</i>';
        i_ret = oSipSessionCall.mute('audio'/*could be 'video'*/, bMute);
        if (i_ret != 0) {
            txtCallStatus.innerHTML = '<i>Mute failed</i>';
            return;
        }
        oSipSessionCall.bMute = bMute;
        // btnMute.value = "Unmute";
}

.

function sipunMute() {
    if (oSipSessionCall) {
        var i_ret;
        var bMute = false;
        txtCallStatus.innerHTML =  '<i>Unmute the call...</i>'
        i_ret = oSipSessionCall.mute('audio', bMute);
        if (i_ret != 0) {
            txtCallStatus.innerHTML = '<i> Unmute failed</i>';
            return;
        }
        oSipSessionCall.bMute = bMute;
        //btnMute.value = "Mute";
    }

如果您有两个不同的按钮，比如 btnMute 和 btnUnmute，那么您不需要 btnMute.value...。

假设您的 oSipSessionCall.bMute 属性:

的初始状态为 false（未静音）

var oSipSessionCall = {
  bMute: false
}

您可以使用一个切换功能来使您的播放器静音和取消静音（我假设您使用的是 jQuery 并且您的按钮的名称为属性 toggle） :

$('[name=toggle]').on('click', function() {
  var i_ret;

  if (oSipSessionCall) {
    txtCallStatus.innerHTML = oSipSessionCall.bMute ? '<i>Mute the call...</i>' : '<i>Unmute the call...</i>';
    i_ret = oSipSessionCall.mute('audio'/*could be 'video'*/, oSipSessionCall.bMute);

    if (i_ret !== 0) {
      txtCallStatus.innerHTML = '<i>Mute failed</i>';
      return;
    }

    oSipSessionCall.bMute = !oSipSessionCall.bMute;
  }
});
