Function USR (){

VaR img_arrow = Document. getelementbyid ("img_arrow ");

If (img_arrow.src.indexof ("arrow_left")> = 0 ){

// Shrink the left arrow name of arrow_left and the right arrow name of arrow_right

Img_arrow.src = img_arrow.src.replace ("arrow_left", "arrow_right"); // switch the arrow picture

Document. getelementbyid ("s4-leftpanel"). style. Display = "NONE"; // hide the left navigation bar

Document. getelementbyid ("mso_contenttable"). Style ["margin-left"] = "10px"; // modify and reduce the right-side navigation bar margin-left. The Arrow image width is 10px.

}
