I am trying to run a function onclick of any button with class="stopMusic" .(我正在尝试使用class="stopMusic"对任何按钮运行onclick函数。)
var stopMusicExt = document.getElementByClass("stopButton");
stopButton.onclick = function() {
var ta = document.getElementByClass("stopButton");
document['player'].stopMusicExt(ta.value);
ta.value = "";
};
ask by user547794 translate from so
You probably meant document.getElementsByClassName() (and then grabbing the first item off the resulting node list):(您可能是指document.getElementsByClassName() （然后从结果节点列表中获取第一项）：)
var stopMusicExt = document.getElementsByClassName("stopButton")[0];
stopButton.onclick = function() {
var ta = document.getElementsByClassName("stopButton")[0];
document['player'].stopMusicExt(ta.value);
ta.value = "";
};
You may still get the error(您可能仍然会收到错误)
document.getElementsByClassName is not a function(document.getElementsByClassName不是函数)
in older browsers, though, in which case you can provide a fallback implementation if you need to support those older browsers.(但是，在较旧的浏览器中，如果需要支持那些较旧的浏览器，则可以提供后备实现。)
