we're going to talk about a conditional statement specifically the if statement in JavaScript and take a look at how we can use that within our coding so what is a conditional statement it is a way to test to see if a condition is true and if it is it's going to run some code if the condition is false it does not run the code so here is the syntax for an if statement we take the word if and right after it within parentheses we put the condition we want to test and what's going to happen is JavaScript is going to go through that condition evaluate if it's true if it's true it runs code that we put below it if this condition is false JavaScript completely skips that code so here's an example of working with a specific code and a specific event within our form so the idea is event target is referencing whatever triggered that particular event to occur which is the form field itself we're assigning that to a variable name and what we're going to do is test the value of that form field and what the user puts into the form field is known as the value so basically this says whatever the user put into the field we're going to test and see if it exactly matches absolutely nothing those are two sets of double quotes so in between we have nothing that means blank so think of it as reading if whatever the user put into that particular form field is blank then we're going to do something and what we're going to do is pop up an alert letting them know they did not enter anything in the field so let's go over to a form and do that so close out of this forum save the changes and let's move out here so we want to test to see if anything was entered into a form field so let me just use the job title form field here as an example so we need to get to the JavaScript piece and I'm going to go over to the actions it will be not mouseup I want it on blur in other words as the user leaves the field I'm going to test this so I'll add it on blur and here's my JavaScript so let's write out that code we just looked at so far user info equals event target so that's creating the variable called user info now we're going to test our condition and what we're going to do is test to see if user info dot value so user info dot value exactly matches the single equal sign is an assignment operator taking the value on the right and putting it into the value on the left or the variable usually and what the double equal sign does it's a comparison operator it's going to compare two different things and the two different...
