我有一个php文件，我正在从php发送变量到ajax文件，一切都运行得很好，但是当我在ajax文件中运行javascript 没有任何东西看起来像警告一个消息，没有任何东西出现，ajax和javascript之间是否有任何冲突？ 这是在ajax文件

答案 0 :(得分：0)
要在ajax调用后运行javascript函数，您应该执行以下操作
$.ajax({
url: "getcode.php?user="+str+"&qty="+qty+"&custid="+custid+"&warehouseid="+warehouseid,
type:"get",
success: function(responseText) {
$("#txtHint").html(responseText);
$("#txtHint").find("script").each(function(i) {
eval($(this).text());
});
}
});
将您的javascript函数放入success函数中..
因此，当ajax调用成功时，该函数将触发
修改
根据您的编码，您需要在功能中进行更改
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
alert('something') // put some javascript here
}
