我的功能运行良好。但我似乎无法在使用 onclick 功能时隐藏按钮或显示新按钮。
样本:
var download = document.getElementById('download');
function RemoveDoc(Doc)
{
xmlhttp=new XMLHttpRequest();
xmlhttp.open("GET","functions/remove.php?Doc="+Doc,true);
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
download.syle.visibility='hidden';
download.style.display ='none'
document.getElementById("RemoveMsg").innerHTML= xmlhttp.responseText;
}
}
xmlhttp.send();
return false;
}
我的表格
//I tried to add in the download button to be hidden here but still invalid
<input type="submit" id="remove" name="Name" value="Remove" onclick="return RemoveDoc(this.value); document.getElementById('download').style.visibility='hidden'; return false;" />
<input type="submit" id="download" value="download"/> //want to hide this button.
<input type="file" id="reupload"/> //want to show this.
我试过 display = 'none' 也无效,因为我的下载在函数调用成功后消失。好心提醒
