问题
I have added a numbered page-navigation script on my Blogger and it is working fine with all pages except the search results page (the page shown with results when I make a search for posts) -- it is showing default "previous post and newer posts" on that page.
Actually I didn't know too much about JavaScript therefore I need help to modify the given JavaScript so that it works also on search result page as like Wordpress.
I am happy to supply any additional needed details.
Thanks in advance... :-)

Firstly you will have to modify the search box, Changing the form action attribute from
action="/search/max-results=12"
to
action="/search/"
Specifiy the max-results parameter as a hidden input field
<input type='hidden' name='max-results' value="12" />
Secondly in the JavaScript code above, search for the following line -
if (thisUrl.indexOf("?q=") == -1 && thisUrl.indexOf(".html") == -1)
and replace it with -
if (thisUrl.indexOf(".html") == -1)
The above condition (aka thisUrl.indexOf("?q=") == -1) was stopping the script to work on pages with a query parameter named q in the URL
Edit 1: For showing correct Page Numbers on Search results pages
Search for the following function in the above code -
function redirectpage(numberpage) {
jsonstart = (numberpage - 1) * perPage;
noPage = numberpage;
var nameBody = document.getElementsByTagName('head')[0];
var newInclude = document.createElement('script');
newInclude.type = 'text/javascript';
newInclude.setAttribute("src", home_page + "feeds/posts/summary?start-index=" + jsonstart + "&max-results=1&alt=json-in-script&callback=finddatepost");
nameBody.appendChild(newInclude)
}
Replace it with -
function redirectpage(numberpage) {
jsonstart = (numberpage - 1) * perPage;
noPage = numberpage;
var nameBody = document.getElementsByTagName('head')[0];
var newInclude = document.createElement('script');
newInclude.type = 'text/javascript';
if(urlactivepage.indexOf("?q=") == -1){
newInclude.setAttribute("src", home_page + "feeds/posts/summary?start-index=" + jsonstart + "&max-results=1&alt=json-in-script&callback=finddatepost");
} else {
newInclude.setAttribute("src", home_page + "feeds/posts/summary?start-index=" + jsonstart + "&alt=json-in-script&q="+ urlactivepage.split("?")[1].split("q=")[1].split("&")[0] +"&callback=finddatepost");
}
nameBody.appendChild(newInclude);
}
Then search for the following block of code -
function pagecurrentg() {
var thisUrl = urlactivepage;
if (thisUrl.indexOf("/search/label/") != -1) {
if (thisUrl.indexOf("?updated-max") != -1) {
postLabel = thisUrl.substring(thisUrl.indexOf("/search/label/") + 14, thisUrl.indexOf("?updated-max"))
} else {
postLabel = thisUrl.substring(thisUrl.indexOf("/search/label/") + 14, thisUrl.indexOf("?&max"))
}
}
if (thisUrl.indexOf("?q=") == -1 && thisUrl.indexOf(".html") == -1) {
if (thisUrl.indexOf("/search/label/") == -1) {
currentPage = "page";
if (urlactivepage.indexOf("#PageNo=") != -1) {
currentPageNo = urlactivepage.substring(urlactivepage.indexOf("#PageNo=") + 8, urlactivepage.length)
} else {
currentPageNo = 1
}
document.write("<script src=\"" + home_page + "feeds/posts/summary?max-results=1&alt=json-in-script&callback=totalcountdata\"><\/script>")
} else {
currentPage = "label";
if (thisUrl.indexOf("&max-results=") == -1) {
perPage = 20
}
if (urlactivepage.indexOf("#PageNo=") != -1) {
currentPageNo = urlactivepage.substring(urlactivepage.indexOf("#PageNo=") + 8, urlactivepage.length)
} else {
currentPageNo = 1
}
document.write('<script src="' + home_page + 'feeds/posts/summary/-/' + postLabel + '?alt=json-in-script&callback=totalcountdata&max-results=1" ><\/script>')

}
and replace it with -

}
}
if (thisUrl.indexOf(".html") == -1) {
if (thisUrl.indexOf("/search/label/") == -1) {
currentPage = "page";
if (urlactivepage.indexOf("#PageNo=") != -1) {

}
if(thisUrl.indexOf("q=") == -1){
document.write("<script src=\"" + home_page + "feeds/posts/summary?max-results=1&alt=json-in-script&callback=totalcountdata\"><\/script>")
} else {
document.write("<script src=\"" + home_page + "feeds/posts/summary?q=" + thisUrl.split("?")[1].split("q=")[1].split("&")[0] + "&alt=json-in-script&callback=totalcountdata\"><\/script>")

}
if (urlactivepage.indexOf("#PageNo=") != -1) {
currentPageNo = urlactivepage.substring(urlactivepage.indexOf("#PageNo=") + 8, urlactivepage.length)
} else {
currentPageNo = 1
}
document.write('<script src="' + home_page + 'feeds/posts/summary/-/' + postLabel + '?alt=json-in-script&callback=totalcountdata&max-results=1" ><\/script>')
}
}
}
Then search for the following block of code
function finddatepost(root) {
post = root.feed.entry[0];
var timestamp1 = post.published.$t.substring(0, 19) + post.published.$t.substring(23, 29);
var timestamp = encodeURIComponent(timestamp1);
if (currentPage == "page") {
var pAddress = "/search?updated-max=" + timestamp + "&max-results=" + perPage + "#PageNo=" + noPage
} else {
var pAddress = "/search/label/" + postLabel + "?updated-max=" + timestamp + "&max-results=" + perPage + "#PageNo=" + noPage
}
location.href = pAddress
}
and replace it with -
function finddatepost(root) {
post = root.feed.entry[0];
var timestamp1 = post.published.$t.substring(0, 19) + post.published.$t.substring(23, 29);
var timestamp = encodeURIComponent(timestamp1);
if (currentPage == "page") {
if(urlactivepage.indexOf("?q=") == -1){
var pAddress = "/search?updated-max=" + timestamp + "&max-results=" + perPage + "#PageNo=" + noPage
} else {
var pAddress = "/search?updated-max=" + timestamp + "&q="+ urlactivepage.split("?")[1].split("q=")[1].split("&")[0] +"&max-results=" + perPage + "#PageNo=" + noPage
}
} else {
var pAddress = "/search/label/" + postLabel + "?updated-max=" + timestamp + "&max-results=" + perPage + "#PageNo=" + noPage
}
location.href = pAddress
}
In all these blocks of code, I have added extra conditions to handle the query parameter conditon. In case you are getting confused, then the new files as a whole looks like - this . An working example can be checked here - https://prayagverma.blogspot.com/?q=Tweet .
Note: Also I had remove the max-results from the JSON API calls above as they were affecting the openSearch$totalResults.$t parameter (which it normally shouldn't)
