IT Specialist HTML5 Application Development Sample Questions:
You are creating a script that reads a JSON menu file and displays the Entree, Price, and Description.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Correct Answer:
Explanation:
First drop-down: var xhr = new XMLHttpRequest();
Second drop-down: if(xhr.status===200){
Third drop-down: responseObject = JSON.parse(xhr.responseText);
The script must first create an XMLHttpRequest object, so the correct first selection is var xhr = new XMLHttpRequest();. This object performs the asynchronous request for menu.json. After the request finishes, the onload callback executes. The response should be processed only when the request succeeds, so the correct status check is if(xhr.status===200){; HTTP status 200 means the file was successfully retrieved.
Status codes 403, 404, and 500 represent forbidden access, missing resource, and server error conditions, so they are not appropriate for normal JSON processing. The JSON file is returned as plain text through xhr.
responseText, so it must be converted into a JavaScript object with JSON.parse(xhr.responseText). Once parsed, the code can access responseObject.menu[i].Entree, Price, and Description inside the loop and build the display output. responseXML is incorrect because the source file is JSON, not XML.

Move the appropriate attributes from the list on the left to the correct descriptions on the right. You may use each attribute once, more than once, or not at all.
Note: You will receive partial credit for each correct match.
Correct Answer:
Explanation:
pattern # Provides a way to set a regular expression that the value must match placeholder # Provides a way to set default text that displays until focus is placed in an element required # Provides a way to set form elements as mandatory multiple # Provides a way to allow more than one file or email address in a single input The correct matches are based on standard HTML5 form validation and input-attribute behavior. The pattern attribute defines a regular expression that the input value must satisfy before the form can be submitted successfully. It is commonly used for structured values such as phone numbers, codes, postal formats, or custom identifiers. The placeholder attribute supplies short hint text inside an input field, helping the user understand the expected value before entering data. The required attribute makes a form control mandatory; if the field is empty, constraint validation prevents successful submission. The multiple attribute allows a single input to accept more than one value, specifically for controls such as input type= " file " and input type= " email " , where users may upload multiple files or enter multiple email addresses. The maxlength attribute is not used in these matches because it limits the maximum number of characters that can be entered, but none of the listed descriptions asks for character-length restriction.
