javascript - Function runs on parent window instead of child -

this runs bookmarklet.

the creation of windows, extracting of values, , writing them window "log" works perfect.

i want save contents of "log" window scrypt.txt, contents of parent window saved instead. did wrong?

javascript: setinterval(logging,60000); w1 = window.open("https://scrypt.cc/index.php"); log = window.open("");  function logging(){     if(w1.document.body.innerhtml == 'server busy. please try again later.'){         w1.location.href = 'https://scrypt.cc/index.php';         console.log("busy");     }else{         console.log("ok");         log.document.body.innerhtml = '';         var re=/var\s*dayprofitperkhs\s*=\s*([0-9\.]+)\s/gi;         var matches=re.exec(w1.document.body.innerhtml);         log.document.write(regexp.$1 + "<p></p>");         log.document.write(w1.$('#t9_2').val() + "<p></p>");         log.settimeout(save,1000);         w1.location.href = 'https://scrypt.cc/index.php';     } } function save() {     = log.document.createelement('a');     a.href = log.location.href;     a.download = 'scrypt.txt';     log.document.body.appendchild(a);     a.click();     a.parentnode.removechild(a); } 

edit: saving *.html, a.href works perfectly:

a.href = 'data:text/html;base64,' + btoa(log.document.body.outerhtml); a.download = 'values.html'; 

your save() function using document of main window. if want run in log() context, need use log.document , log.location.

function save() {     = log.document.createelement('a');     a.href = log.location.href;     a.download = 'scrypt.txt';     log.document.body.appendchild(a);     a.click();     a.parentnode.removechild(a); } 

this guess, try moving saving code script tag in log window this:

setinterval(logging, 60000); var w1 = window.open("https://scrypt.cc/index.php"); var log = window.open("");  function logging() {     if (w1.document.body.innerhtml == 'server busy. please try again later.') {         w1.location.href = 'https://scrypt.cc/index.php';         console.log("busy");     } else {         console.log("ok");         log.document.body.innerhtml = '';         var re = /var\s*dayprofitperkhs\s*=\s*([0-9\.]+)\s/gi;         var matches = re.exec(w1.document.body.innerhtml);         log.document.write(regexp.$1 + "<p></p>");         log.document.write(w1.$('#t9_2').val() + "<p></p>");          // insert script tag create save link , click         var sc = "<scr" + "ipt>";         sc += "function save() {";         sc += "var = document.createelement('a');";         sc += "a.href = location.href;";         sc += "a.download = 'scrypt.txt';";         sc += "document.body.appendchild(a);";         sc += "a.click();";         sc += "a.parentnode.removechild(a);";         sc += "}";         sc += "settimeout(save, 1000);";         sc += "</scr" + "ipt>";         log.document.write(sc);          w1.location.href = 'https://scrypt.cc/index.php';     } }
