jquery - Show div with the same data-attribute as select option attribute -


i show divs set display none in css depending on multiple if statements. want use data-attributes , data value match data value of hidden div.

the options:

<select class="selectoptions" id="selectoptions1">     <option data-name="man">         man1     </option>     <option data-name="woman">         woman     </option>     <option data-name="child">         child     </option>    </select>  <select class="selectoptions" id="selectoptions2">     <option data-age="30">         man1     </option>     <option data-age="25">         woman     </option>     <option data-age="10">         child     </option>    </select>

hidden divs:

<div class="datatest" data-age="25" data-name="man">hey man</div> <div class="datatest" data-age="20" data-name="woman">hello woman</div> <div class="datatest" data-age="10" data-name="child">hi child</div>

and js:

$('.selectoptions').on('change', function() {    var agevalue = $('#selectoptions2 option:selected').data('age');   var namevalue = $('#selectoptions1 option:selected').data('name');  // alert(namevalue + ' ' + agevalue);    $('.datatest').filter(function() {     return this.dataset.name === namevalue || this.dataset.age === agevalue   }).css("display", "block").siblings(".datatest").css("display", "none"); });

the values of data attributes on change found correctly alert showing them, can not use variables in conditions. welcome. thanks.

try utilizing .filter() select .datatest element, siblings() hide selected .datatest siblings

$('.selectoptions').on('change', function() {          var agevalue = $(':selected', this).data('age');        var namevalue = $(':selected', this).data('name');        var filtered = agevalue || namevalue;        alert(filtered);          $('.datatest').filter(function() {          var name = this.dataset.name, age = this.dataset.age;          return name == filtered || age == filtered         }).css("display", "block").siblings(".datatest").css("display", "none");      });
.datatest {    display: none;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>  <select class="selectoptions" id="selectoptions1">      <option data-name="man">          man1      </option>      <option data-name="woman">          woman      </option>      <option data-name="child">          child      </option>     </select>    <select class="selectoptions" id="selectoptions2">      <option data-age="30">          man1      </option>      <option data-age="25">          woman      </option>      <option data-age="10">          child      </option>     </select>  <div class="datatest" data-age="25" data-name="man">hey man</div>  <div class="datatest" data-age="20" data-name="woman">hello woman</div>  <div class="datatest" data-age="10" data-name="child">hi child</div>

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
