Question

javascript innerHTML 能不能用数组

<script language="javascript" type="text/javascript">
var xmlHttp = false;
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e2) {
xmlHttp = false;
}
}
if (!xmlHttp && typeof XMLHttpRequest != 'undefined') {
xmlHttp = new XMLHttpRequest();
}

function callServer(aa,cc) {
bb=cc
// alert(ProdId);
var url = "66.asp?name=" + aa;

xmlHttp.open("GET", url, true);
xmlHttp.onreadystatechange = updatePage;
//alert(updatePage);
xmlHttp.send(null);
//alert("updatePage");
}
function updatePage() {
//var test="test"+bb;
alert(bb);
var test=new Array();
if (xmlHttp.readyState < 4) {

test.innerHTML="正在读取价格";
}
if (xmlHttp.readyState == 4) {
var response= xmlHttp.responseText;
test.innerHTML=response;

}
}
</script>
<input name="ProdId" type="button" onClick="callServer('20002718',0);" value="提交" size="20" maxlength="15"/>

<span id="test[0]">555</span><br>

下面这一行能不能改成数组test[bb]
test.innerHTML=response;

Answer 1

楼主貌似是想把response的内容插入到数组的某个元素中而不是整个数组内吧？test.innerHTML=response;改成test[bb].innerHTML=response;是完全可以的，只要bb不溢出就可以了
<script language="javascript" type="text/javascript">
var xmlHttp = false;
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e2) {
xmlHttp = false;
}
}
if (!xmlHttp && typeof XMLHttpRequest != 'undefined') {
xmlHttp = new XMLHttpRequest();
}

function callServer(aa,cc) {
var url = "66.asp?name=" + aa;
bb=cc;
xmlHttp.open("GET", url, true);
xmlHttp.onreadystatechange = updatePage;
xmlHttp.send(null);
}
function updatePage() {
var test=document.getElementById("test"+bb);
if (xmlHttp.readyState < 4) {
test.innerHTML="正在读取价格";
}
if (xmlHttp.readyState == 4) {
var response= xmlHttp.responseText;
test.innerHTML=response;

}
}
</script>
<input name="ProdId" type="type" size="20" maxlength="15" onClick="callServer();"/>
<input name="ProdId" type="button" onClick="callServer('20002718',0);" value="提交" size="20" maxlength="15"/>
<span id="test0">555</span><br>
<input name="ProdId" type="type" size="20" maxlength="15" onClick="callServer();"/>
<input name="ProdId" type="button" onClick="callServer('20002718',1);" value="提交" size="20" maxlength="15"/>
<span id="test1">555</span><br>

Answer 2

test.innerHTML=test[bb].toString();

Answer 3

不能，必须为字符串
