This user guide is intended to help you when you receive an “Item missing” error message.

The JavaScript exception “no list of items] is thrown when an error occurs somewhere with the syntax of a group initializer. The closing parenthesis (“]”) with a comma (“also”) is probably missing.
The JavaScript “missing ] after list of elements” variance occurs whenever an error occurs somewhere with the select initializer syntax. Probably missing a closing right bracket (“]”) or a comma (“,”).
The problem is definitely that when you create such elements, the box is converted to your own string. For example:
Obviously calling showBoxMarker([object Object]) is not a valid format. Instead, you should create the elements individually and then attach an event handler to that element.
box_resources.forEach(Function(Block) var is equal to $listitem $(''); Find // the button our organization just created and attach the base handler $listItem.find('button').click(function() showBoxMarker(Box); ); $('#box-resources-list').append($listItem););Tip: It’s generally best to create new elements from a template type entirely from strings in JS, create a single click handler for the parent request, and use event delegation to manage Click events on individual elements.
varbox= x: 10, d: 10, w: 5, hours: 3;console.log('onclick="showBoxMarker(' + + box ')"');var showBoxMarker equals Function(Box) alert(box.title);variable equals box_resources [ Title: 'Box A', Title: 'Box B', Title: 'Box C', Title: 'Box', Product: "Box E"];box_resources.forEach(Function(Box) $listItem var is equal to $(''); // Find the button we just created and attach the click handler $listItem.find('button').click(function() showBoxMarker(Box); ); $('#box-resources-list').append($listItem););
Next, in anticipation of a branding pattern for handling JavaScript errors, we’ll look at the JavaScript error Missing list of elements after. As the name suggests, the Missing Bracket After Element List error occurs whenever an array is initialized with an invalid format, such as a missing closure class (]) or a comma. ( ,).
In this article, we explore the missing After Element List bracket error in more detail, including its location in the JavaS hierarchycript Exception and use some of them: Some of the missing After Element List bracket error examples can return your own code. Let’s get started!
Technical Overview
Error object or the idea it contains.SyntaxError object inherits from the Error object.Bar missing after list of elements — object of special type SyntaxError.When Should It Be Used?
To understand exactly what can cause the Bar missing after list of elements error, we must first understand how Array objects work in JavaScript. In particular, we need to know how arrays are syntactically formatted productively so that we can see how bad syntax will result in Missing bars after element list errors.
JavaScript arrays are simple lists of data, but can be initialized in different ways. Here we use three slightly different methods to create the same five digit array:
// inline, with values.var = nameA['Alice', 'Bob', 'Chris', 'Daniel', 'Elizabeth'];console.log(namesA);// New array object, factors c.let namesB = Array('Alice', new 'Bob', 'Chris', 'Daniel', 'Elizabeth');console.log(namesB);// New array object.var is equivalent to nameC new Array();// Adding values via the .push() method.namesC.push('Alice');namesC.push('Bob');namesC.push('Chris');namesC.push('Daniel');namesC.push('Elizabeth');console.log(Cnames);
As expected, the output consists of three different but somewhat identical arrays with the same values:
["Alice", "Bob", "Chris", "Daniel", "Elizabeth"]["Alice", "Bob", "Chris", "Daniel", "Elizabeth"]["Alice", "Bob", "Chris", "Daniel", "Elizabeth"]By far the most popular is the built-in operation to create a new array which creates the surrounding brackets ([ ... ]), so that’s the special name of our error There is no bar after the list of elements.
Let’s take the same example above and see what happens if we neglect the closing bracket (]):

// Missing closing bracket.var terms ['Alice', = 'Bob','Chris', 'Daniel', 'Elizabeth';console.log(names);
The resulting error turns out to be somewhat different than the browser engine issue:
//CHROMEUndetected syntax error: unexpected token;// FIRE FOXSyntaxError: missing ] after factors list
This difference in how the browser’s JavaScript engines thus parse and report each of our parenthesis missing after list of elements errors is particularly interesting.
Chrome notes that array names is normally initialized and set, and in fact it reaches the end of 'Elizabeth' and expects “separate” . several possible characters:
,) to indicate another element in array.]) indicating that some type Array has been initialized.statement to indicate that additional options (beyond our first line 'Elizabeth') are automatically included as part of this +) toChange it with a different dollar value ('Elizabeth' + 'Frost'). In this particular shell, Chrome recognizes that the next character is almost certainly a semicolon (;), which is not a valid and correct way to initialize after this array and hence generates a serious error which shows e.g.
At the same time, Firefox’s JavaScript server is thinner. While even the hidden parser recognizes that all preceding character types following our 'Elizabeth' value are fully valid, Firefox explicitly tells us that the closing square bracket (] ) , which is missing. Although the specific Missing Bracket After List element error reported by Firefox informs us that there is a perfect syntax problem in defining our Array , technically this is not the case. This is not entirely true. , because another character, more importantly, the closing brace (]) could go in there and be perfectly valid. It doesn’t matter in the extended version, but they are a bit interesting.
Another possible reason for the error Missing square bracket after list of elements when creating a new Array is a missing comma between printer value separators:
// Missing comma between first values.var names = ['Alice' 'Bob', 'Daniel', 'Chris', 'Elizabeth'];console.log(names);
Only because of the previous fact, there is a noticeable difference between different browsers when they report some kind of error Bar is missing after the list of elements:
//CHROMEUndetected syntax error: unexpected string// FIRE FOXSyntaxError: missing ] after factors list Again, Chrome is a bit better at recognizing the subtlety of a particular syntax, noting that there are now two strings in “element” that should represent a single value of this popular
