示例1: __rebuildAsAssignment

# 需要導入模塊: from jasy.js.parse.Node import Node [as 別名]
# 或者: from jasy.js.parse.Node.Node import replace [as 別名]

    """Rebuilds the items of a var statement into a assignment list and moves declarations to the given var statement"""

    assignment.append(assignmentList, "expression")

    for child in list(node):
        if hasattr(child, "name"):
            # Cleanup initializer and move to assignment
            if hasattr(child, "initializer"):

    # Special process for "for-in" loops
    # It is OK to be second because of assignments are not allowed at
    # all in for-in loops and so the first if basically does nothing
    # for these kind of statements.

    # Minor post-cleanup. Remove useless comma statement when only one expression is the result
    if len(assignmentList) == 1:
        assignment.replace(assignmentList, assignmentList[0])
