javascript - Cuts off form data when setting url as value -


this script creates cookie depending on form data, (ex: ?docname=my document)

<script type="text/javascript"> { var docname = getvalue("docname"); // these go off script form data     var save = getvalue("save");     var url = window.location.href; } function setcookie(name, value, days) {     if (days) {         var date = new date();         date.settime(date.gettime() + (days * 24 * 60 * 60 * 1000));         var expires = "; expires=" + date.togmtstring();     }     else var expires = "";     document.cookie = name + "=" + value + expires + "; path=/"; } function savedoc() {     if (docname != '') {         setcookie(docname,url,730);     }     else {      // nothing else     } } // helps find errors if exist window.onerror = function(errormessage, url, line) {     var errortext = 'message: ' + errormessage + '\nurl: ' + url + '\nline: ' + line + ' please contact us, , report error.';     alert(errortext); } </script>

it creates cookie , sets name of docname variable, when sets url value, cuts off form data.

i've researched , changed code couldn't find answer, can help?

solution

<script type="text/javascript"> { var docname = getvalue("docname"); // these go off script form data     var save = getvalue("save");     var url = window.location.href;     var recode = encodeuricomponent(url);  } function setcookie(name, value, days) {     if (days) {         var date = new date();         date.settime(date.gettime() + (days * 24 * 60 * 60 * 1000));         var expires = "; expires=" + date.togmtstring();     }     else var expires = "";     document.cookie = name + "=" + value + expires + "; path=/"; } function savedoc() {     if (docname != '') {         setcookie(docname,recode,730);     }     else {      // nothing else     } } // helps find errors if exist window.onerror = function(errormessage, url, line) {     var errortext = 'message: ' + errormessage + '\nurl: ' + url + '\nline: ' + line + ' please contact us, , report error.';     alert(errortext); } </script>

changed variable used set value recode , set recode equal encodeuricomponent(url); decodes url, decoding , making possible have form data in value or name of cookie, etc. @epascarello

encodeuricomponent() friend here

document.cookie = name + "=" + encodeuricomponent(value) + expires + "; path=/";

and when it, need decode decodeuricomponent().

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
