      @htilburgs said in Uncaught SyntaxError: Unexpected token return:

        }		
        return table;		
      

      u have an extra close brace, which matches up with the getDom() {
      and so, that return is just hanging out there

        @sdetweil , thanx, missed that.
        Now that this part is running the JSON data is fetched. But when I trying to show the data I get an error:

        Uncaught SyntaxError: Unexpected number
        

        This error is created by the zero in the line:
        WoonplaatsCell.innerHTML = MWB.0.plaats;

        		var MWB = this.MWB;
        
        		// creating the tablerows
        		var WoonplaatsRow = document.createElement("tr");
        		WoonplaatsRow.className = "woonplaats-row";
        		
        		var WoonplaatsCell = document.createElement("td");
        		WoonplaatsCell.className = "small";
        		WoonplaatsCell.innerHTML = MWB.0.plaats;
        		WoonplaatsRow.appendChild(WoonplaatsCell);
        		table.appendChild(WoonplaatsRow);
        

        The problem seems that I cannot use the 0 in the command.

        This is the JSON result

        object{1}
        	liveweer[1]
        		0{49}
        			alarm: "0"
        			d0neerslag: "4"
        			d0tmax: "12"
        			plaats: "Amsterdam"
        			...
        

        I used a JSON checker and it says that it’s valid JSON.
        How do I display the data from this result, if I cannot use the 0?

        (still trying to learn JS, but not afraid to ask) ☺

          use a variable to hold the value

          var x = 0

          WoonplaatsCell.innerHTML = MWB.x.plaats;
          or use a literal

          WoonplaatsCell.innerHTML = MWB.[‘0’].plaats;

            No luck…
            I’ve tried both of the options:

            	var MWB = this.MWB;
            	var n = 0;
            
            	// creating the tablerows
            	var WoonplaatsRow = document.createElement("tr");
            	WoonplaatsRow.className = "woonplaats-row";
            	
            	var WoonplaatsCell = document.createElement("td");
            	WoonplaatsCell.className = "small";
            	WoonplaatsCell.innerHTML = MWB.n.plaats;
            	WoonplaatsRow.appendChild(WoonplaatsCell);
            	table.appendChild(WoonplaatsRow);
            

            Error: Uncaught (in promise) TypeError: Cannot read property ‘plaats’ of undefined

            	var MWB = this.MWB;
            
            	// creating the tablerows
            	var WoonplaatsRow = document.createElement("tr");
            	WoonplaatsRow.className = "woonplaats-row";
            	
            	var WoonplaatsCell = document.createElement("td");
            	WoonplaatsCell.className = "small";
            	WoonplaatsCell.innerHTML = MWB.['0'].plaats;
            	WoonplaatsRow.appendChild(WoonplaatsCell);
            	table.appendChild(WoonplaatsRow);
            

            Error: Uncaught SyntaxError: Unexpected token [

            So both of the options give an error.

              sorry, my bad, try these

              WoonplaatsCell.innerHTML = MWB[n].plaats;
              WoonplaatsCell.innerHTML = MWB['0'].plaats;

                @sdetweil YES, that did the trick! Learning a lot these few days.
                Thanks again.

                Is this notation always like this if you’re working with numbers?

                  @htilburgs not so much numbers, but variable data… the notation

                  MWB.n.plaats
                  

                  means the plaats element of the n element of MWB
                  so the dot notation treats the between dot things as literals…

                  a number can’t be a variable name literal in this sense…
                  so, you need the bracket notation [] (and remove the left side dot when u use it this way)
