Extract phone number from a Web Page

标签： javascript autohotkey

I want to get phone number from this Web Page with WinHttpRequest. There is javascript which changes digits in random order - I can not understand the algorithm.

http://www.doska.ru/msg/work/courses-education/seminari-un-trenini/ailoo.html

Here is code on autohotkey:

WebRequest := ComObjCreate("WinHttp.WinHttpRequest.5.1")
WebRequest.Open("GET", "http://www.doska.ru/msg/work/courses-education/seminari-un-trenini/ailoo.html", false)
WebRequest.Send()
Body := WebRequest.ResponseBody
pArr := ComObjValue(Body)
cBytes := NumGet(pArr+0, A_PtrSize = 8? 24:16, "uint")
pText := NumGet(pArr+0, A_PtrSize = 8? 16:12, "ptr")
var := StrGet(pText, cBytes, "utf-8")
RegExMatch(var, "id=""ph_td_2"">(.+?)</span>", phone)
msgbox % phone1

The script that generates phone number seems to be:

<script type="text/javascript">open_stat_lnk("");change_price( 8, 0, "", 0 );show_banner( );
var show_code = "Наберите текст с картинки"; var show_phone = "Показать номер"; var pcc_id=0;
print_phone(PH_2,2,0);if( PH_c && !pcc_id ){pcc_id=2;eval(PH_c);}
</script>

Function print_phone(PH_2,2,0) I found here: http://i.doska.ru/w_inc/js/main.ru.doska.js?v=251

function print_phone(d, k, b) {
    var g = el("ph_td_" + k);
    if (!g) {
        g = el("ph_td")
    }
    if (!g || !d) {
        return
    }
    var f = p2 = _js_decode(d);
    if (b) {
        var c = el("ptd2_" + k);
        if (c) {
            c = c.innerHTML;
            c = c.split("<");
            c = c[0];
            c = c.replace("(", "");
            c = c.replace(")", "");
            p2 = f.replace("-", "");
            p2 = p2.replace("-", "");
            p2 = p2.replace("-", "");
            p2 = c + "" + p2
        }
        g.innerHTML = '<a href="tel:' + p2 + '">' + f + "</a>"
    } else {
        g.innerHTML = f
    }
    g.style.visibility = "visible"
}

Please help me with this puzzle.

您正在致电：print_phone(PH_2,2,0); 所以，你的值就像输入一样。

d := PH_2, 
k := 2, 
b := 0

你在做：

if (0) { // do some stuff } else { display(f); }

由于b == 0，0的值为false;你只是在显示f。

f是_js_decode(d)

这是在做什么：

function _js_decode(b){ // PH_2
    return _ph_dec(b,"Hb9c0mOswgV4p{zDlf",2);
}

function _ph_dec(g,r,k){ // PH_2, "Hb9c0mOswgV4p{zDlf", 2
                         // Your issue might be there ?
    g=unescape(_b64_dec(g));
    var n=r.length; // 18
    var d=g.length;
    var c="";
    var q,p;
    for(var f=0;f<d;f++){
        q=g.substring(f,f+1); // take the g[f] char
        p=r.substring(f%n,f%n+1); // take g[f%n] char
        if(k==1){
            q=q.charCodeAt(0)-p.charCodeAt(0) // not the case we are looking for !
        } else {
            if(k==2) {
                // why the '14' is here ? 
                q=q.charCodeAt(0)-p.charCodeAt(0)+14 // the case we are looking for !
            } else {
                q=q.charCodeAt(0)^p.charCodeAt(0) // not the case we are looking for !
            }
        }
   c=c+String.fromCharCode(q)
   }
   return c
 }

假设thenchanter是正确的并且顺序总是相同的，那么这将完成工作：

mainHtml := HtmlGet("http://www.doska.ru/msg/work/courses-education/seminari-un-trenini/ailoo.html")
RegExMatch(mainHtml, "<td width=100% class=""ads_contacts"" nowrap id=""ptd2_[^""]*"">([^<]+)<span class=""ads_contacts_bold"" id=""ph_td[^""]*"">([^<]+)</span>", phone)
