var nodeWordsString = document.getElementById("nodeWordsTextArea").value.trim();
var nodeWordsStringArray=nodeWordsString.split(" ");
var strLength = nodeWordsStringArray.length;
for(int i = 0; i < nodeWordsStringArray.length; i++)----->******
{
for(int j = 0; j < nodeWordsStringArray.length; j++)
{
if(nodeWordsStringArray(i) == nodeWordsStringArray(j))
{
alert("Node duplication occurred at:"+nodeWordsStringArray(i));
return false;
//break;
}

This is javascript, but you're using intin your loop declaration? Try replacing those with varinstead.
这是javascript，但您int在循环声明中使用？尝试将它们var替换为。

变化int i和int j以var i和var j。

In my case, the error was caused by using letin the loop. Old browsers like Firefox 38 doesn't support let.
就我而言，错误是由let在循环中使用引起的。Firefox 38 等旧浏览器不支持let.
Replacing letby varsolved the issue.
let通过替换var解决了问题。

If you are here in 2016, maybe you are trying to use a letdeclaration outside strict mode in a browser that does not yet support it. Replace it with varor add 'use strict;'to the top of your function.
如果您在 2016 年在这里，也许您正试图let在尚不支持严格模式的浏览器中使用严格模式之外的声明。将其替换为var或添加'use strict;'到函数的顶部。

var strLength = nodeWordsStringArray.length;
for(int i = 0; i < nodeWordsStringArray.length; i++)
You can use for (int i = 0; i < strLength; i++)it is more efficient. As for your actual error try moving your brackets to the end of your for line. for(..;..;..) {
你可以使用for (int i = 0; i < strLength; i++)它更有效率。至于您的实际错误，请尝试将括号移到 for 行的末尾。for(..;..;..) {
P.S. as mentioned there is no int.
PS如上所述没有int。
