jquery - How to jump to a particular page's some drop-down's particular value using JavaScript? -


suppose have drop-down "page2.html":

page2.html

<div id="mydropdownlink">     <select id="first-drop" name="first-drop">         <option value="select state">select steate</option>         <option value="ny">new york</option>         <option value="nj">new jersey</option>     </select> </div>

now, "page1.html", have link like

page1.html

<a href="abc.html" id="mylink">go page 1</a>

so goal is:

on click of link, go "page2.html" , select second drop down value , selected. example, select second drop down value ie "nj" one. can programmatically?

i able go specific page drop-down location. failed select second value form drop-down.

window.location.href = forwardedwebsitelink + "?" + "#first-drop";

any idea can this?

you combine 2 things: uri anchors (adding # in uri) , parameters (? followed values) make example.com#first-drop?firstdropdown=nj

in javascript (on page2.html) you'd have this:

//run script on page load.  window.onload = function() {    var url = window.location.href;      //let me cheat since don't have page1 , page2 in example...    url += "#firstdropdown?firstdropdown=ny";      // select text after # , before ? symbol.    var dropdown = url.substring(url.indexof('#') + 1, url.indexof('?') - 1);        // select text after ? symbol    var selectedoption = url.substring(url.indexof('?') + 1);      // filter dropdown's id , value object.    selectedoption = {      elem: selectedoption.substring(0, selectedoption.indexof('=')),      value: selectedoption.substring(selectedoption.indexof('=') + 1)    };      // dropdown domelement in page can change selectedindex.    dropdown = document.queryselector('#' + selectedoption.elem);        var index = 0, selectedindex = 0;      // loop through dropdown's children element find right one.    dropdown.childnodes.foreach(function(elem, i) {      // make sur domelement nodes only.      if (elem.nodetype == 1) {           if (elem.value === selectedoption.value) {          elem.setattribute("selected", "selected");          selectedindex = index;          return true;        }        index++;      }    });    // have right index, let's make sure it's selected.    dropdown.selectedindex = selectedindex;  }
<select id="firstdropdown">    <option value="nj">new jersey</option>    <option value="ny">new york</option>    <option value="la">los angeles</option>  </select>

running snippet select new york city.
