(tbl = document.getElementById("content_value')īut it can't find the table, it will assign the variable tbl = undefined Īt this point, the script will continue to work. If your assigning a variable, for example, assigning the table main table to a variable To be clear on the error, the moment it can't do something with a value it has, it will crash. In this case, we have forseen that eventually, the index would be greater than the coord array length, and have coded specifically for this situation. Had the index not been assigned to zero (or some other value within range), the script would have crashed, as there is often no error handling code in scripts that don't cover specific problems. Yes, if the index value is larger than the coordinate list, it will (in this example), set the index to 0 (zero), display the information that it has exceeded the list length, then it will (later in the script) overwrite the cookie with the new index. Given we know it comes out as a text object, we need to convert it to an int, before we can use it for anything mathematical/numerical.ĮxampleString = "9" <- This is a string ĮxampleInteger = 8 <- This is an integer ĮxampleString = parseInt(exampleString) <- This is now an integerĮxampleInteger = exampleInteger.toString() <- This is now a string, though unnecessary, as ints can become strings on their own. This however doesn't happen in javascript, so when we need to use it as something its not, it needs to be told to change it. In the majority of other languages, things are automatically converted to the type of object your treating them as on the fly. As such, because we intend to actually use the contents of it as an integer, we must get the contents, strip the unwanted data (because cookies aren't actually quite plain text), then force it to be an integer (parseInt(someVariable)). JavaScript is actually called ECMA script, or ECMA-262.įarmcookie is a plain text item, that we expect to just be an index integer. Java is a programming language, whereas as the name implies, javascript, is a scripting language. To be clear, Java and JavaScript are not the same thing. But then began to give issues and now is at a state where I click and sometimes it will work and sometimes (alot more often than not) it won't. I was using this bookmark script to farm sequentially, and it worked perfectly for a while. I'm a non premmy player using OPERA on Windows 7 in World 60.
