如何在选择任何下拉值时显示/隐藏 DIV？

Question

I have found many answers to the question:

How do I show/hide DIV on selection of "Other" dropdown value.

However I cannot find the answer to this: How do I show/hide div on selection of ANY dropdown value, eg

<select class="default" id="security_question_1" name="security_question_1">
        <option value="" selected>Select question...</option>
        <option value="1">Question One</option>
        <option value="2">Question Two</option>
        <option value="3">Question Three</option>
        <option value="4">Question Four</option>
        <option value="5">Question Five</option>
        <option value="6">Question Six</option> 
    </select>

I want to be able to show a DIV if any of the above options are selected.

When the user selects 1, 2, 3, 4, 5, or 6 I want to show a DIV. If the user reverts their selection back to "Select question..." this DIV will hide again

A JSfiddle solution would be perfect

Many thanks!

Answer 1

Javascript

var elem = document.getElementById("security_question_1");
elem.onchange = function(){
    var hiddenDiv = document.getElementById("showMe");
    hiddenDiv.style.display = (this.value == "") ? "none":"block";
};

HTML

<select class="default" id="security_question_1" name="security_question_1">
        <option value="" selected>Select question...</option>
        <option value="1">Question One</option>
        <option value="2">Question Two</option>
        <option value="3">Question Three</option>
        <option value="4">Question Four</option>
        <option value="5">Question Five</option>
        <option value="6">Question Six</option> 
    </select>
<div id="showMe">Value Selected</div>

CSS

#showMe{
    display:none;
}

Try this:

HTML:

<div>
        <select>
            <option value="choose">Choose Color</option>
            <option value="red">Red</option>
            <option value="green">Green</option>
            <option value="blue">Blue</option>
        </select>
    </div>
    <div class="choose box">You have to select <strong>any one option</strong> so i am here</div>
    <div class="red box">You have selected <strong>red option</strong> so i am here</div>
    <div class="green box">You have selected <strong>green option</strong> so i am here</div>
    <div class="blue box">You have selected <strong>blue option</strong> so i am here</div>

Javascript:

$(document).ready(function(){
        $("select").change(function(){
            $( "select option:selected").each(function(){
                if($(this).attr("value")=="red"){
                    $(".box").hide();
                    $(".red").show();
                }
                if($(this).attr("value")=="green"){
                    $(".box").hide();
                    $(".green").show();
                }
                if($(this).attr("value")=="blue"){
                    $(".box").hide();
                    $(".blue").show();
                }
                if($(this).attr("value")=="choose"){
                    $(".box").hide();
                    $(".choose").show();
                }
            });
        }).change();
    });

Answer 3

add the following function to the onchange,

function showHide(value) {
    if (value=='')
        document.getElementById('divShow').style.display = 'none';
    else
        document.getElementById('divShow').style.display = 'block';
}

and set the display style of the div (which is needed to hide/shown) to none initially. Check demo here

Answer 4

Try this -

$( "#security_question_1" ).change(function () {
    if($( "option:selected", this ).text()=="text you want to match"){
       $("#div-id").hide();
    }else{
       $("#div-id").show();        
    }
});

Answer 5

<select class="default" id="security_question_1" name="security_question_1">
        <option value="" id="hide-div"selected>Select question...</option>
        <option value="1" id="show-div">Question One</option>
        <option value="2" id="show-div">Question Two</option>
        <option value="3" id="show-div">Question Three</option>
        <option value="4" id="show-div">Question Four</option>
        <option value="5" id="show-div">Question Five</option>
        <option value="6" id="show-div">Question Six</option> 
    </select>

$(document).ready(function(){
   $(".spl-div").hide();   
   $("option[id*='show-div']").bind('click', function(){
            $('.spl-div').show();
    });
    $("option[id*='hide-div']").bind('click',function(){
            $(".spl-div").hide();
    })
});

Answer 6

Try this :

Javascript :

function check_dd() {
    if(document.getElementById('security_question_1').value == "") {
        document.getElementById('test').style.display = 'none';
    } else {
        document.getElementById('test').style.display = 'block';
    }
}

HTML :

<select class="default" id="security_question_1" name="security_question_1" onchange="check_dd();">
    <option value="" selected>Select question...</option>
    <option value="1">Question One</option>
    <option value="2">Question Two</option>
    <option value="3">Question Three</option>
    <option value="4">Question Four</option>
    <option value="5">Question Five</option>
    <option value="6">Question Six</option> 
</select>

<div id="test" style="display:none;">test</div>

Answer 7

Why don't use event? like the following:

<select class="default" id="security_question_1" name="security_question_1" onchange="itemChange(this)">
        <option value="" selected>Select question...</option>
        <option value="1">Question One</option>
        <option value="2">Question Two</option>
        <option value="3">Question Three</option>
        <option value="4">Question Four</option>
        <option value="5">Question Five</option>
        <option value="6">Question Six</option> 
</select>
<div id="content" style="visibility:hidden">selection result
</div>

function itemChange(sender) {
    var c = document.getElementById("content");
    if (sender.value > 0) {
        c.innerHTML = sender.value;
        c.style.visibility = "visible";
    } else {            
        c.innerHTML = "selection result";   
        c.style.visibility = "hidden";
    }
}

Answer 8

This worked for me , this is a more powerful method because use the has and contain method so you can use wildcards

$( "YOURSELECT" ).change(function () {
if($("YOURSELECT").has('option:selected:contains(YourWord)').length){
$("ELEMENT-TO-HIDE-IF-CONDITION-MATCH").hide();
}else{
$("ELEMENT-TO-HIDE-IF-CONDITION-MATCH").show();        
}
});

Answer 10

You can use jQuery's change() method in combination with show() and hide() methods. The div blocks in the following example are hidden by default using the CSS display property, which is set to none .

$(document).ready(function(){
    $("select").change(function(){
        $(this).find("option:selected").each(function(){
            var val = $(this).attr("value");
            if(val){
                $(".msg").not("." + val).hide();
                $("." + val).show();
            } else{
                $(".msg").hide();
            }
        });
    }).change();
});
