ios和andorid已做好
web的怎么做？
var myElement = document.createElement("input") //(2)给元素添加必要的标示信息 myElement.type = "button"; myElement.id = "dofileselect"; myElement.style.display = "none"; //添加到document.body document.body.appendChild(myElement); // var e = document.createEvent("MouseEvents"); // e.initEvent("click", true, true); myElement.click();
这个代码无效
