根据下拉列表中选择的选项显示文本

Question

I have a dropdown like below.

<label for="form_name">Title</label>
<select class="bootstrap-select">
  <option value="1" selected="selected">Feature 1</option>
  <option value="2">Feature 2</option>
  <option value="3">Feature 3</option>
  <option value="4">Feature 4</option>
</select>
<div><p>Text1</p></div>
<div><p>Text2</p></div>
<div><p>Text3</p></div>
<div><p>Text4</p></div>

I intend to show Text 1 when Feature 1 is selected, Text 2 when Feature 2 is selected and so on.

Any ideas on how can I do this with JS (or jQuery)?

PS Most existing solutions require input field rather than options field or maybe I am too noob. xD

Answer 1

Give the p tags the id as the value of the options , and show the p tag when selected option has the value which is equal to the id of p

 $('p').hide(); $('#1').show(); $('select').change(function() { $('p').hide(); var a = $(this).val(); $("#" + a).show(); })

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <label for="form_name">Title</label> <select class="bootstrap-select"> <option value="1" selected="selected">Feature 1</option> <option value="2">Feature 2</option> <option value="3">Feature 3</option> <option value="4">Feature 4</option> </select> <div> <p id="1">Text1</p> </div> <div> <p id="2">Text2</p> </div> <div> <p id="3">Text3</p> </div> <div> <p id="4">Text4</p> </div>

With pure javascript

 let select = document.querySelector("select"); let divs = document.querySelectorAll("div"); let result = document.querySelector("#result"); function func1(par){ result.innerText = divs[par - 1].innerText; }

 div:not(#result) { display:none; }

 <label for="form_name">Title</label> <select class="bootstrap-select" onchange="func1(this.value)"> <option value="1" selected="selected">Feature 1</option> <option value="2">Feature 2</option> <option value="3">Feature 3</option> <option value="4">Feature 4</option> </select> <div><p>Text1</p></div> <div><p>Text2</p></div> <div><p>Text3</p></div> <div><p>Text4</p></div> <div id="result"></div>

 function display(){ var e = document.getElementById("dropDownId"); var index = e.selectedIndex; if(index==0){ document.getElementById("first").style.display = 'block' document.getElementById("second").style.display = 'none' } else if(index==1){ document.getElementById("first").style.display = 'none' document.getElementById("second").style.display = 'block' } }

 <label for="form_name">Title</label> <select class="bootstrap-select" id="dropDownId" onchange="display()"> <option value="1" selected="selected">Feature 1</option> <option value="2">Feature 2</option> </select> <div id="first"><p>Text1</p></div> <div id="second" style="display: none;"><p>Text2</p></div>

You can use ids on your div that you want to show and change the value of your select with the ids you choosed

 $("#select-panel").change(function(){ updateDisplay(); }) function updateDisplay(){ var idToShow = $("#select-panel").find(":selected").val() || "div1"; $(".subcontent").each(function(){ $(this).css("display",$(this).is("#"+idToShow) ? 'block' : 'none'); }) } updateDisplay();

 .subcontent{ display:none; }

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <select id="select-panel"> <option value="div1">1</option> <option value="div2">2</option> </select> <div id="div1" class="subcontent">Text 1</div> <div id="div2" class="subcontent">Text 2</div>
