javascript - window.opener doesn't work in firefox and chrome but in IE -


i have problem window.opener function (js):

i created 3 simple pages simulate problem:

test.php:

<html>     <head>     </head>     <body>         <input type="button" onclick="window.open('first_page_in_popup.php', 'popup', 'width=470,height=500');">             <input type="text" id="content" name="content" >     </body> </html>

first_page_in_popup.php:

<html>     <head>         <script type="text/javascript" >             window.opener.document.getelementbyid('content').value= "test first page in popup";             window.open('second_page_in_popup.php', 'popup');         </script>     </head>     <body>     </body> </html>

second_page_in_popup.php:

<html>     <head>         <script type="text/javascript" >             window.opener.document.getelementbyid('content').value= "test second page in popup";         </script>     </head>     <body>     </body> </html>

result: in ie, input field has content "test second page in popup". in chrome , firefox, content : "test first page in popup".

the error message:

window.opener.document.getelementbyid(...) null

i solved problem changing code of page "first_page_in_popup.php" to:

<html>     <head>         <script type="text/javascript" >             window.opener.document.getelementbyid('content').value= "test first page in popup";             window.location.href = 'second_page_in_popup.php';          </script>     </head>     <body>         <p> first page </p>          <input type="text" id="first" name="first">     </body> </html>

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
