tag, add an empty script element.

3. 6. Below the calcTotalfunction, add the following code to create an event listener: Within the acript element, add the following code to declare the calcTotal) function and its variables: 1 add event 11stener to Submit button 2 v r8ubmiButton-doeunent.geLElementById("aButton"); 3 if submitButton.addEventListener) { 1 // function to add values of selected check boxes and display total submitButton.addEventListener ("click", calcTotal, false) olse if(submitButton.attachEvent) function calcTotal0 5 var itemTotal-0 var tax = 0; var totalWithTax 0; var items document.getElementaByTagName ("input" var celis document.getElementsByagName (ta) submitButton.attachEvent("onellck", caleTotal) 7. Save your changes to index.htm, open index.htm in a browser, check the Fried halibut and Side salad boxes, click Calculate, and then verify that your page displays an Item total of 15.9, Tax of 0.80, and Total with tx of $16.78, as shown in Figure 7-21 4. Before the closing,enter the following for statement: 1for (var i-015: 1++) if (itens [i].checked) { Hands-on Project 7-3 itemTotal t: items [1].value 1); Lunch selections Fried chicken ($7.99) Fried halibut ($9.99) Hamburger ($7.99) Grilled salmon ($12.99) Side salad ($5.99) Item total 15.98 0.80 $16.78 Total with tax This statement loops through all of the check boxes in the form.
