I have the below code to show a form for admin to create, suspend accounts
echo "<FORM name=\"admin\" action=\"\" enctype=\"multipart/form-data\">";
echo "<select onchange=\"ChangeType();\" name=\"action\" id=\"action\">";
echo "<option value=\"select\">--Select--</option>";
echo "<option value=\"create\">Create Account</option>";
echo "<option value=\"suspend\">Suspend Account</option>";
echo "</select><br><br>";
echo "<div id=\"data\">";
echo "</div>";
echo "<input type=\"button\" name=\"button\" onclick=\"AccountAction()\" value=\"Submit\">";
echo "<input type=\"reset\" id=\"reset\" value=\"Reset\" onclick=\"ResetForm();\">";
echo "</FORM>";
and the javascript to dynamically create elements within the DOM when the user calls ChangeType()
function ChangeType()
{
var type = document.getElementById("action").options[document.getElementById("action").selectedIndex].value;
if(type=="select")
{
document.getElementById('data').innerHTML = "";
}
if(type=="create")
{
document.getElementById('data').innerHTML = "<input id=\"username\" placeholder=\"Username\" type=\"text\" name=\"username\"><br><br>";
document.getElementById('data').innerHTML += "<input id=\"password\" placeholder=\"Password\" type=\"password\" name=\"password\"><br><br>";
return;
}
if(type=="suspend")
{
document.getElementById('data').innerHTML = "<input id=\"username\" placeholder=\"Username\" type=\"text\" name=\"username\"><br><br>";
return;
}
}
the code works fine however i cannot get the placeholder for the dynamically created username and password input types
i have already looked at Adding jQuery placeholders to dynamically created form elements
but it doesn't help as the placeholders only appear when i click within the textarea once and then click outside.
You have to do like this :
document.getElementById('data').setAttribute("placeholder", "placeholder value");
In your code :
function ChangeType() {
var type = document.getElementById("action").options[document.getElementById("action").selectedIndex].value;
if (type == "select") {
document.getElementById('data').innerHTML = "";
document.getElementById('data').setAttribute("placeholder", "placeholder value");
}
if (type == "create") {
document.getElementById('data').innerHTML = "<input id=\"username\" placeholder=\"Username\" type=\"text\" name=\"username\"><br><br>";
document.getElementById('data').innerHTML += "<input id=\"password\" placeholder=\"Password\" type=\"password\" name=\"password\"><br><br>";
document.getElementById('data').setAttribute("placeholder", "placeholder value");
return;
}
if (type == "suspend") {
document.getElementById('data').innerHTML = "<input id=\"username\" placeholder=\"Username\" type=\"text\" name=\"username\"><br><br>";
document.getElementById('data').setAttribute("placeholder", "placeholder value");
return;
}}
Using Jquery (browser compatible solution) :
$("#data").attr("placeholder", "placeholder value");
Works for me:
HTML
<FORM name="admin" action="" enctype="multipart/form-data">
<select onchange="ChangeType();" name="action" id="action">
<option value="select">--Select--</option>
<option value="create">Create Account</option>
<option value="suspend">Suspend Account</option>
</select><br><br>
<div id="data"></div>
<input type="button" name="button" onclick="AccountAction()" value="Submit">
<input type="reset" id="reset" value="Reset" onclick="ResetForm();">
<!--This button alerts all palceholder attributes for all input tags within the div-->
<input type="button" name="button" onclick="checkPlaceHolder()" value="Check Placeholder Values">
</FORM>
Javascript
function AccountAction(){}
function ResetForm(){}
function ChangeType() {
var type = document.getElementById("action").options[document.getElementById("action").selectedIndex].value;
if(type=="select")
{
document.getElementById('data').innerHTML = "";
}
if(type=="create")
{
document.getElementById('data').innerHTML = "<input id=\"username\" placeholder=\"Username\" type=\"text\" name=\"username\"><br><br>";
document.getElementById('data').innerHTML += "<input id=\"password\" placeholder=\"Password\" type=\"password\" name=\"password\"><br><br>";
return;
}
if(type=="suspend")
{
document.getElementById('data').innerHTML = "<input id=\"username\" placeholder=\"Username\" type=\"text\" name=\"username\"><br><br>";
return;
}
}
function checkPlaceHolder() {
$( '#data input' ).each(function(o) {
alert('Placeholder : ' + $(this).attr('placeholder'));
});
}
The function checkPlaceHolder
alerts all the input tag placeholder attributes within the div
tag. Hope this helps.
