我在JavaScript中有两个函数并收到以下错误：
参数列表之后的Uncaught SyntaxError：missing）
它没有给我一个行号，我似乎无法找到罪魁祸首;我将不胜感激：
function makeRequest() {
var xmlhttp = new XMLHttpRequest();
console.log('reached');
xmlhttp.onreadystatechange = function() //This part is actually executed last
{
console.log("within");
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) // Was the request processed successfully?
{
console.log(location);
console.log(xmlhttp.responseText);
first = xmlhttp.responseText.substring(xmlhttp.responseText
.search('first:') + 6, xmlhttp.responseText
.search(',last'));
console.log("First: " + first);
last = xmlhttp.responseText.substring(xmlhttp.responseText
.search(',last') + 6, xmlhttp.responseText
.search(',utt'));
console.log("last: " + last);
utt = xmlhttp.responseText.substring(xmlhttp.responseText
.search(',utt') + 5, xmlhttp.responseText
.search(',type'));
console.log("utt: " + utt);
type = "";
attribute = "";
out = "";
index = "";
values = "";
if (xmlhttp.responseText.search(',att') > -1) {
type = xmlhttp.responseText.substring(
xmlhttp.responseText.search(',type') + 6,
xmlhttp.responseText.search(',att'));
//attribute
pass = xmlhttp.responseText.substring(
xmlhttp.responseText.search(',att') + 5,
xmlhttp.responseText.search(',vals'));
values = xmlhttp.responseText.substring(
xmlhttp.responseText.search(',vals') + 7,
xmlhttp.responseText.search(']}'));
} else {
type = 'instance';
//index
pass = xmlhttp.responseText
.substring(xmlhttp.responseText
.search('indexResult:') + 12,
xmlhttp.responseText.search(',inst:'));
out = xmlhttp.responseText.substring(
xmlhttp.responseText.search('inst:') + 5,
xmlhttp.responseText.search('}'));
}
console.log("type: " + type);
if (type === 'attribute') {
vals = values.split(",");
html = "You have said the following to the virtual assistant: </br><i>'"

+ attribute.toLowerCase().substring(0,
attribute.length - 1)

for (i = 0; i < vals.length; i++) {

}

，另一个功能是：

return false;

{
console.log(location);
console.log(xmlhttp.responseText);
type = xmlhttp.responseText.substring(
xmlhttp.responseText.search(',type') + 6,
xmlhttp.responseText.search(',att'));
attribute = xmlhttp.responseText.substring(
xmlhttp.responseText.search(',att') + 5,
xmlhttp.responseText.search(',vals'));
values = xmlhttp.responseText.substring(
xmlhttp.responseText.search(',vals') + 7,
xmlhttp.responseText.search(']}'));
vals = values.split(",");
console.log("type: " + type);
if (xmlhttp.responseText.search(',att') > -1) {
type = xmlhttp.responseText.substring(
xmlhttp.responseText.search(',type') + 6,
xmlhttp.responseText.search(',att'));
//attribute
pass = xmlhttp.responseText.substring(
xmlhttp.responseText.search(',att') + 5,
xmlhttp.responseText.search(',vals'));
values = xmlhttp.responseText.substring(
xmlhttp.responseText.search(',vals') + 7,
xmlhttp.responseText.search(']}'));
} else if (xmlhttp.responseText.search('instance') > -1) {
type = 'instance';
//index
pass = xmlhttp.responseText
.substring(xmlhttp.responseText
.search('indexResult:') + 12,
xmlhttp.responseText
.search(',inst:'));
out = xmlhttp.responseText.substring(

xmlhttp.responseText.search('}'));
} else {
type = 'done';
}
if (type === 'attribute') {
vals = values.split(",");

HTML是：
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
<script>
window.onload = function init() {
server = window.location.host;
params = location.search.split("?")[1];
first = params.split("&")[0].split("=")[1];
last = params.split("&")[1].split("=")[1];
}
</script>
</head>
<body>
<div id="utteranceDiv">
When you are ready click Submit and the system will begin to ask you
questions in an attempt to find you a restaurant that you are happy
with.</br> <input type="button" onclick="return makeRequest()"
value="Select"></input>
</div>
<script type="text/javascript">
//see above for javascipt
</script>
</body>
</html>
第一次通话后div会更新：
<div id="utteranceDiv">
You have said the following to the virtual assistant: <br><i>'i want a
mexican restaurant at 7 pm in cupertino'
</i><br><br>Given that you have said this; <br> How about null. It is in
Mountain View; in Peninsula. There is a reservation at earlyNight.<br>
<select id="choice" name="attribute"><option selected="selected"
value="makeSelection">please choose</option>
<option value="yes">yes</option>
<option value="no">no</option></select><br><br><input type="button"
onclick="return sendChoice(eli,pincus,i want a mexican restaurant at 7 pm in
cupertino,instance,1)" value="Submit"></div>
答案 0 :(得分：0)
我检查你的帖子，但我找不到任何遗失的“）”。控制台不会告诉你在哪里看？
答案 1 :(得分：0)
我明白了;这是因为在更新的页面上写的javascript函数的参数是字符串，所以需要围绕它们的qoutes（其中一个有空格，这就是为什么我没有得到一个行号，它弄乱了解析器）< / p>
