示例1: createLoop
import org.mozilla.javascript.ast.Jump; //导入方法依赖的package包/类
private Node createLoop(Jump loop, int loopType, Node body,
Node cond, Node init, Node incr)
{
Node bodyTarget = Node.newTarget();
Node condTarget = Node.newTarget();
if (loopType == LOOP_FOR && cond.getType() == Token.EMPTY) {
cond = new Node(Token.TRUE);
}
Jump IFEQ = new Jump(Token.IFEQ, cond);
IFEQ.target = bodyTarget;
Node breakTarget = Node.newTarget();
loop.addChildToBack(bodyTarget);

if (loopType == LOOP_WHILE || loopType == LOOP_FOR) {
// propagate lineno to condition
