Set it as the homepage and the Javascript code added to the favorites folder (it is compatible with IE, Firefox, chrome, and other browsers)

Because chrome, safari, and opara Browsers Do not support automatic "set as Homepage" & "add to Favorites", we can only try and catch and give an error message! It's perfect.

In Internet Explorer, many people have encountered an error in window. external. addFavorite., so I had to throw a prompt.

Add to favorites:
Copy codeThe Code is as follows:
Function addFavorite (){
If (document. all ){
Try {
Window. external. addFavorite (window. location. href, document. title );
} Catch (e ){
Alert ("failed to add to favorites, please add with Ctrl + D ");
}

} Else if (window. sidebar ){
Window. sidebar. addPanel (document. title, window. location. href ,"");
} Else {
Alert ("failed to add to favorites, please add with Ctrl + D ");
}
}

Set as homepage:
Copy codeThe Code is as follows:
Function setHomepage (){
If (document. all ){
Document. body. style. behavior = 'url (# default # homepage )';
Document. body. setHomePage (window. location. href );
} Else if (window. sidebar ){
If (window. netscape ){
Try {
Netscape. security. PrivilegeManager. enablePrivilege ("UniversalXPConnect ");
} Catch (e ){
Alert ("this operation is rejected by the browser. If you want to enable this function, enter about: config in the address bar, and set the value of signed. applets. codebase_principal_support to true ");
}
}
Var prefs = Components. classes ['@ mozilla.org/preferences-service%1'}.getservice (Components. interfaces. nsIPrefBranch );
Prefs. setCharPref ('browser. startup. homepage', window. location. href );
} Else {
Alert ('your browser does not support automatic homepage settings. Please use the browser menu to manually set it! ');
}
}
