History. back () is the previous page
I = 1
History. go (I) goes to a specified page
If it is history. go (0), it is to refresh these two JS codes, which is equivalent to IE's forward and backward functions.
The specific use depends on when this is needed. For example, the user registration verification is background verification, and this can be used when the user does not meet the requirements, to ensure that the user does not input data repeatedly to the maximum extent.
For example, load a page:
Function onLoadPage (){
If (event. srcElement. tagName = "SPAN "){
OFrame = top. window. middle. frames [2];
OTxt = event. srcElement. innerText;
Switch (oTxt ){
Case "Forward ":
OFrame. history. go (1 );
Case "back ":
OFrame. history. back ();
Case "refreshing ":
OFrame. location. reload ();
}
}
}
