javascript - How to open different URLs by checkbox? -


this html , javascript code

<input type="text" id="text" />  <input type="button" id="btn" value="submit" onclick="javascript: window.open('http://example.com/' + document.getelementbyid('text').value);" />

if input anytext in form box , click on submit button, open http://example.com/anytext. want add 3 checkbox named page1 page2 , page3 under form. if click on checkbox page1 , click on submit button, open http://example.com/page1/anytext

how can it?

you create function processes value of checkboxes , returns string need insert window.open call. this:

onclick="javascript: window.open('http://example.com/' +getradiovalue() + document.getelementbyid('text').value);"

also, note snippet won't redirect when click submit due sandbox restrictions on it, can see error in browser console , page code attempts redirect to.

function getradiovalue () {    var cb1 = document.getelementbyid("cb1");    var cb2 = document.getelementbyid("cb2");    var cb3 = document.getelementbyid("cb3");        if(cb1.checked) {      return "page 1/";    } else if(cb2.checked) {      return "page 2/";    } else if(cb3.checked) {      return "page 3/";    } else {      return "";    }  }
<input type="text" id="text" />  <br/>  <label>  <input type="checkbox" value="page 1" id="cb1" />  page 1  </label>  <br/>  <label>  <input type="checkbox" value="page 2" id="cb2" />  page 2  </label>  <br/>  <label>  <input type="checkbox" value="page 3" id="cb3" />  page 3  </label>  <br/>  <input type="button" id="btn" value="submit" onclick="javascript: window.open('http://example.com/' +getradiovalue() + document.getelementbyid('text').value);" />

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
