Instruction Keyword

import

---

import “./../case.lc2”

Import another case or more.You should write the code before process main,or you can click the button in the toolbar of Case-Editor to complete import.

The case below shows how to import $BUTTON in Magic Keyword.

//Import the case named "rightclick.lc2"
import "./rightclick.lc2";
process main () {
    // New Page
    jumpto "https://www.github.com/";
    wait 2333;
    rightclick ("a:contains('Sign up')");//Here we use process rightclick() from the case "rightclick.lc2"
}

The case “rightclick.lc2” shows below.

//This is a sub-process simulating right-click with $BUTTON.​
process rightclick(a) {
    $BUTTON = "right";
    click a;
}

process

---

process main{ }
process sub{ }

Define a process,including process main and process sub.

//This is a main process.
process main(){

}

//This is a sub process which can be named with different keywords without special characters (except 'main').
process anyname(){ 

}

return

---

return [expression];

Ends process execution(and specifies a value to be returned). A process immediately stops at the point where return is called.

process main () {
  log square(10);
  return;
  log "Mi";
}

process square(x){
    log 1+1;
    return x*x;
    log "Smartisan";
}
//Output:
//2 first,output 1+1 in process square
//100 next,output 100 in process main
//"Smartisan" will not appear cause the process square has already stopped
//"Mi" will not appear cause the process main has already stopped

for…in

---

for (variable in object){ }

Iterates over the enumerable properties of an object, in original insertion order. For each distinct property, statements can be executed.

process main () {
    // for...in(array)
    X=["Smartisan","Mi"];
    for (i in X){
    log "X[" +i+ "]="+ X[i];
  }

    // for...in(array)
    A = {1:1,2:2};
    for (a in A){
    log "A["+a+"]="+A[a];
  }
}
//Output:
//X[0]=Smartisan
//X[1]=Mi
//A[1]=1
//A[2]=2

for…of

---

for (variable of object){ statement }

Creates a loop iterating over iterable objects, invoking a custom iteration hook with statements to be executed for the value of each distinct property.

process main () {
  // for...of(string),Iterating over a String.
  B = "Lemonce";
  for (b of B){
    log b;
  }

  // for...of(array),Iterating over an Array.
  C = [20,30,40];
  for (c of C){
    log c;
  }
}

//Output
//L
//e
//m
//o
//n
//c
//e
//20
//30
//40

if…else

---

if (condition)
statement1
[else
statement2]

Executes a statement if a specified condition is truthy. If the condition is falsy, another statement can be executed.

process main () {
a=4;
x=a*a;
if (x< 9){
    log "1";
 }
else if (x==9){
    log x;
    log "2";
 }
else {
    log "3";
 }
}
//Output "3"

continue

---

continue;

Terminates execution of the statements in the current iteration of the current or labeled loop, and continues execution of the loop with the next iteration.

process main () {
i = 0;
n = 0;
while (i < 5) {
   i=i+1;
   if (i === 3) {
      continue;
   }
   n += i;
   log n;  //Output 1,3,7,12
   }
}

while

---

while (condition)
statement

Creates a loop that executes a specified statement as long as the test condition evaluates to true. The condition is evaluated before executing the statement.

process main () {
    counter();   
    }  
process counter() {
    count = 1;
    while(count < 5){        // count=1,2,3,4
        log count + 'A';
        count +=1;
        log count + 'B';    // count=2,3,4,5
      }
    return;
    log count + 'C';        // This statement never appears. 
}

log

---

log [expression,variable,string];

Output a message to the console. You can output variables, expressions, strings etc. that have been defined in the test case.

log '2'+3;    //Output  23
log true;    //Output  true
