javascript - onClick Window.Location does not work in Chromium (Linux version of Google Chrome) -

I think I'm stupid or something else, but I do not get my onClick to work through Chromium There is a Linux version of Chrome (Firefox is OK, as is IE)

Here are some HTML code:

  & lt; Form & gt; & Lt; Select name = "month" & gt; & Lt; Option value = "1" onclick = "javascript: window.location.href = '& lt; SOPAGE & gt;' Return Return; '' Jan & lt; / Option & gt; & lt; Option Value = "2" & gt; February & lt; / Option & gt; & lt; Option Value = "3" & gt; March & Lt; / option & gt; Option value = "4"> April  gt; option value = "5" & gt; May & lt; / option & gt; & Lt; option value = "6"> Jun & lt; / option & gt; Option value = "7" & gt; July & lt; / option & gt; & lt; option value = "8" "> August  gt; Option value =" 9 "& gt; September & lt; / option & gt; Option value =" 10 "& gt; October & lt; / Option & gt; & lt; option value = "11" & gt; Vambar & lt; / option & gt; option value = "12" & gt; December & lt; / options & gt; & lt; / select & gt; & lt; / form & gt;  

I believe that the use of the option elements on the onClick is not supported on all browsers. That if it can still be that there are still better ways to do this.

About using the on-change event of selection and then to see which option is selected

& lt; Script language = "javascript" & gt; Function doSomething () {select = document.getElementById ("month") [document.getElementById ("month"). SelectedIndex] .value; Switch (selected) {case "1": window.location.href = 'http: //www.ibm.com'; break; }} & Lt; / Script & gt; & Lt; Select Name = "month" id = "month" onChange = "doSomething ()" & gt; & Lt; Option value = "1" & gt; January & lt; / Options & gt; & Lt; Option value = "2" & gt; February & lt; / Options & gt; & Lt; Option value = "3" & gt; March & lt; / Options & gt; & Lt; Option value = "4" & gt; April & lt; / Options & gt; & Lt; Option value = "5" & gt; May & lt; / Options & gt; & Lt; Option value = "6" & gt; June & lt; / Options & gt; & Lt; Option value = "7" & gt; July & lt; / Options & gt; & Lt; Option value = "8" & gt; August & lt; / Options & gt; & Lt; Option value = "9" & gt; September & lt; / Options & gt; & Lt; Option value = "10" & gt; October & lt; / Options & gt; & Lt; Option value = "11" & gt; November & lt; / Options & gt; & Lt; Option value = "12" & gt; December & lt; / Options & gt; & Lt; / Select & gt; & Lt; / Form & gt;
