The present invention discloses a cross-linking method for a visual programming page. Input and output pin symbols are designed, so that functional ranges can be set and matched keyword attributes can be filled. Matching of the input and output pin symbols is performed by keywords in different functional ranges of an element, a plug-in, an apparatus and the like, and cross-linking symbols are generated according to sequences from left to right and from top to bottom near the pin symbols, wherein the cross-linking symbols record associated page numbers. The cross-linking symbols are double clicked to open associated pages and highlight the matched input and output pin symbols. By forming the cross-linking symbols, a signal transmission relationship between different pages is marked and a data flow relationship is clearly shown.
