![]() Use with caution, because it is a non-standard pattern, despite being valid code. might introduce a lot of visual noise or fragility. under the directions of the programme I think either. if the condition is satisfied to continue running the program in a first direction, if not as the second direction. ![]() ![]() thanks conditional statement we can control program running in two directions. It's pretty simple, and a neat way (if it fits with what you are trying to do) of handling a long series of conditions, where perhaps a long series of ìf(). JavaScript - Conditional statement: if, if else By conditions we can control our program. I've added parentheses here to make it clearer, but they are optional, depending on the complexity of your expression. Write it with if statements instead like this: if (liCount 0) setLayoutState ('start') else if (liCount<5) setLayoutState ('upload1Row') else if (liCount<10) setLayoutState ('upload2Rows') ('UploadList').data ('jsp'). The if.else statement is used to execute a block of code among two alternatives. This expression evaluates to true, meaning this case is run, and terminates at the break. The switch then moves on to the next case true = (liCount0). However, it does work too, so worth keeping in mind to understand what it is doing.Įg: if liCount is 3, the first comparison is true = (liCount = 0), meaning the first case is false. If the condition does prove true, it will execute the code defined inside its code block. but personally prefer dealing with conditions that evaluate to truthyness. An if statement will evaluate if a condition is true. I typically err towards specifying it except when there's no way for someone decently qualified to get confused. The only thing necessary is switch(true) and have the desired expressions evaluate to false instead of true. Can be best practice to include () around a conditional statement - removes any confusion as to order of operations etc.
