Answer 1

            function timer(div){
                inputs = div.getElementsByTagName('input');
                if(inputs[0].value == "")
                    return ;
                window.setInterval(function(){
                    inputs = div.getElementsByTagName('input'); // 你的 inputs 变量是个局部的?
                    alert(inputs[0].value); // 如果确认是全局的,用 window.inputs 试下?
                }, inputs[2].value * 1000);                
            }

Answer 2

我这边试了下，setInterval里是可以取到值的

Answer 3

inputs[2].value 它的值是不是NaN

Answer 4

        <script>
            var xmlhttp,
                inputs;
            function ajax(){
                if(window.XMLHttpRequest){
                    xmlhttp = new XMLHttpRequest();
                }
                else{
                    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
                }
                return xmlhttp;
            }
            function submit(){
                divs = document.getElementsByName('t');
                for(var i = 0;i < divs.length;i++){
                    timer(divs[i]);
                }
                
            }
            function timer(div){
                window.inputs = div.getElementsByTagName('input');
                window.setInterval(function(){
                    alert(window.inputs[0].value);
                }, window.inputs[2].value * 1000);
            }
            
            function sendData(){
                xmlhttp = ajax();
                xmlhttp.open("POST","tiebaSend.do",false);
                xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded;");
                var s = "cookie=" + this.cookie + "&";
                var s = s + "para=" + this.para;
                xmlhttp.send(s);
                addToTextArea(xmlhttp.responseText);
            }
            
            
            function addToTextArea(s){
                var textarea = document.getElementById('response');
                    textarea.value = textarea.value + s + "\r";
            }
        </script>
还是不行么..

Answer 5

看了樓主的js，timer 函數裡的 inputs 不該使用全局變量
加上var 就可以正常了
