blocks|key|1131065|text|此类错误的原因通常是对象或数组定义中的逗号放错了位置：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1131066|var+obj+=+{

}|code-block|syntax|javascript|1131067|如果它出现在任意一行，可能是您动态创建的对象定义的一部分。|1131068|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

The cause of this type of error can often be a misplaced comma in an object or array definition:

<pre><code>var obj = {
 id: 23,
 name: "test", &lt;--
}
</code></pre>

If it appears at a random line, maybe it's part of an object defintion you are creating dynamically.

blocks|key|1131024|text|实际上，我最近在IE上得到了类似的东西，它与JavaScript语法“错误”有关。我把错误放在引号里是因为除了IE，其他地方都没问题。这是在IE6下。该问题与JSON对象创建和额外的逗号有关，例如|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1131025|{+one:1,+two:2,+three:3,+}|code-block|syntax|javascript|1131026|IE6真的不喜欢3后面的逗号。你可能会找这样的东西，敏感的语法形式问题。|1131027|是的，我认为我的25行JavaScript中的数百万行也很有趣。|1131028|祝好运。|1131029|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Actually I got something like that on IE recently and it was related to JavaScript syntax "errors". I say error in quotes because it was fine everywhere but on IE. This was under IE6. The problem was related to JSON object creation and an extra comma, such as

<pre><code>{ one:1, two:2, three:3, }
</code></pre>

IE6 really doesn't like that comma after 3. You might look for something like that, touchy little syntax formality issues.

Yeah, I thought the multi-million line number in my 25 line JavaScript was interesting too.

Good luck.

Just saw the bug in one of my applications, as a catch-all, remember to enclose the name of all javascript properties that are the same as keyword.

Found this bug after attending to a bug where an object such as:

<pre><code>var x = { class: 'myClass', function: 'myFunction'};
</code></pre>

generated the error (class and function are keywords)
this was fixed by adding quotes

<pre><code>var x = { 'class': 'myClass', 'function': 'myFunction'};
</code></pre>

This error occurs when we add or missed to remove a comma at the end of array or in function code. It is necessary to observe the entire code of a web page for such error.

I got it in a Facebook app code while I was coding for a Facebook API.

<pre><code>&lt;div id='fb-root'&gt;
 &lt;script type='text/javascript' src='http://connect.facebook.net/en_US/all.js'&lt;/script&gt;
 &lt;script type='text/javascript'&gt;
 window.fbAsyncInit = function() {
 FB.init({appId:'".$appid."', status: true, cookie: true, xfbml: true});

 // ^ extra comma here

blocks|key|1346282|text|对我来说，这听起来就像是用src拉入的脚本，并且只加载了一半，导致了语法错误，因为其余的都没有加载。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1346283|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

blocks|key|1131500|text|这个bug的另一个变体:我有一个名为'continue‘的函数，因为它是一个保留字，所以它抛出了这个错误。我不得不将我的函数重命名为'continueClick‘|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1131501|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Another variation of this bug: I had a function named 'continue' and since it's a reserved word it threw this error. I had to rename my function 'continueClick'

blocks|key|1131623|text|也许你有一个对象，它有一个“构造函数”方法，并试图调用这个方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1131624|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Maybe you've got an object having a method 'constructor' and try to invoke that one.

blocks|key|1347092|text|您可能会在使用Knockout+JS时遇到此问题。如果您尝试像下面的示例那样设置class属性，它将失败：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1347093|<span+data-bind="attr:+{+class:+something()+}">|code-block|syntax|javascript|1347094|像这样转义类字符串：|1347095|<span+data-bind="attr:+{+'class':+something()+}">|1347096|我的两分钱。|1347097|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

You may hit this problem while using Knockout JS. If you try setting class attribute like the example below it will fail:

<pre><code>&lt;span data-bind="attr: { class: something() }"&gt;&lt;/span&gt;
</code></pre>

Escape the class string like this:

<pre><code>&lt;span data-bind="attr: { 'class': something() }"&gt;&lt;/span&gt;
</code></pre>

My 2 cents.

blocks|key|1347172|text|我也遇到过这个问题。我在下面找到了两个解决方案。1)。与上面提到的一样，从JSON对象中删除多余的逗号。2)。另外，我的JSP/HTML有。正因为如此，它触发了浏览器的旧模式，对于额外的逗号，会给出JS错误。使用时，它会触发浏览器的HTML5模式(如果支持)，即使使用额外的逗号也能正常工作，就像任何其他浏览器FF、Chrome等一样。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1347173|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I too had come across this issue. I found below two solutions.
1). Same as mentioned by others above, remove extra comma from JSON object.
2). Also, My JSP/HTML was having . Because of this it was triggering browser's old mode which was giving JS error for extra comma. When used it triggers browser's HTML5 mode(If supported) and it works fine even with Extra Comma just like any other browsers FF, Chrome etc.

blocks|key|1131817|text|这里有一个调试问题的简单技术:将脚本/代码回显到控制台。将代码从控制台复制到您的IDE中。大多数IDE对代码执行错误检查并突出显示错误。您应该能够在JavaScript/HTML编辑器中几乎立即看到错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1131818|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Here is a easy technique to debug the problem:
echo out the script/code to the console.
Copy the code from the console into your IDE.
Most IDE's perform error checking on the code and highlight errors.
You should be able to see the error almost immediately in your JavaScript/HTML editor.

blocks|key|1131886|text|使用不同的配置时也有同样的问题。这是在angular工厂定义中的，但我假设它也可以在其他地方发生：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1131887|angular.module("myModule").factory("myFactory",+function(){
++++return
++++{
++++++++myMethod+:+function()+//+<---+error+showing+up+here

++++}

Had the same issue with a different configuration. This was in an angular factory definition, but I assume it could happen elsewhere as well:

<pre><code>angular.module("myModule").factory("myFactory", function(){
 return
 {
 myMethod : function() // &lt;--- error showing up here
 {
 // method definition
 } 
 }
});
</code></pre>

Fix is very exotic:

<pre><code>angular.module("myModule").factory("myFactory", function(){
 return { // &lt;--- notice the absence of the return line
 myMethod : function()
 {
 // method definition
 } 
 }
});
</code></pre>

blocks|key|1131996|text|如果你在一个类的中间调用一个函数，那么在Typescript中也会发生这种情况。例如|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1131997|class+Dojo+implements+Sensei+{
+++++console.log('Hi');+//+ERROR+Identifier+expected.
+++++constructor(){}
}|code-block|syntax|javascript|1131998|像console.log()这样的函数调用必须在函数内部。而不是在应该声明类字段的区域中。|offset|length|style|CODE|1131999|entityMap^0|0|0|1|D|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

This can also happen in Typescript if you call a function in middle of nowhere inside a class. For example

<pre><code>class Dojo implements Sensei {
 console.log('Hi'); // ERROR Identifier expected.
 constructor(){}
}
</code></pre>

Function calls, like <code>console.log()</code> must be inside functions. Not in the area where you should be declaring class fields.

blocks|key|1347484|text|我遇到了这个错误，因为在constants.js中使用的不是尾随逗号或类似的语法|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1347485|++++var+titles+=+{

I came across this error where rather than a trailing comma or some such, this syntax had been used in a constants.js

<pre><code> var titles = {
 [title.X]: 'X title',
 [title.Y]: 'Y title'
 }
</code></pre>

IE 11 did not like this at all.

As previously mentioned though this was easily fixed by using 

<pre><code> var titles = {
 'title.X': 'X title',
 'title.Y': 'Y title' 
 }
</code></pre>

Some users are reporting occasional JS errors on my site. The error message says "Expected identifier, string or number" and the line number is 423725915, which is just an arbitrary number and changes for each report when this occurs. 
This mostly happens with IE7/ Mozilla 4.0 browsers.

I scanned my code a bunch of times and ran jslint but it didn't pick anything up - anyone know of the general type of JS problems that lead to this error message?

一些用户在我的网站上偶尔报告JS错误。错误消息显示“期望的标识符、字符串或数字”，行号为423725915，这只是一个任意的数字，当发生这种情况时，每个报告都会发生变化。这主要发生在IE7/ Mozilla 4.0浏览器上。我多次扫描我的代码并运行jslint，但它没有发现任何问题--有人知道导致此错误消息的JS问题的一般类型吗？
