javascript - Change selected option when clicked -


what trying achieve follows:

when user changes selected value in select box, refresh page, add selected text value existing url , reset select box default value selected user before page refresh.

any ideas doing wrong?

html code:

<select class="selectedform">     <option value="one" selected>one</option>     <option value="two">two</option>     <option value="three">three</option>     <option value="four">four</option> </select>

javascript code:

$(".selectedform").change(function() {        $('.selectedform option:contains(' + this.value + ')').prop({selected: true});        alert( $('.selectedform').find(":selected").val() );    if ( window.location.href.indexof("&") > -1 )  {        window.location.search = '?towhere=cursos&q='+$('.selectedform').find(":selected").text();    } else {        window.location.search += '&q='+$('.selectedform').find(":selected").text();    } });

fiddle

to preserve value of selector after reload use like:

$(".selectedform").on('change', function() {   var _loc = string(location.href)       ,loc  = _loc.substr(0, _loc.lastindexof('/'));       self.location.href = loc + '?selected='+this.value; });  // handler load selected option on page load function loadselectedopt() {     var loc = location.search;     if (loc.length) {         $(".selectedform").val(loc.split('=')[1]);     } }

in words: add selected option value querystring of current location (?selected=[selected value]), reload page, , use querystring set value of selector when page reloaded.

here's jsfiddle demo

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 .
