I am new to javascript and html and I am writing a program that displays a dropdown list and depending on what option is selected, I then display two radio buttons and a textfield. I am having trouble getting access to the values of these inputs (both for the radio buttons and for the text box).
<html>
<script type="text/javascript">
window.onload = function()
{
var select = document.getElementById("select");
var texts = document.getElementById("texts");
select.onchange = function()
{
var val = select.options[select.selectedIndex].value;
texts.innerHTML = "";
if (val == "employees")
{
texts.innerHTML += '<div><input type="radio" name="condition_employees" value="select_money" /> ></div>';
texts.innerHTML += '<div><input type="radio" name="condition_employees" value="select_money1" /> <</div>';
texts.innerHTML += '<div><input type="text" name="input_employees" value="select_employees" /></div>';
//var realValue = document.getElementByName('input_employees')[0].value;
//texts.innerHTML += '<div>realValue</div>';
}
if (val == "total_money")
{
texts.innerHTML += '<div><input type="radio" name="condition_money" value="select_money" /> ></div>';
texts.innerHTML += '<div><input type="radio" name="condition_money" value="select_money1" /> <</div>';
texts.innerHTML += '<div><input type="text" name="input_money"' + '" value="select_money" /></div>';
}
if (val == "hits")
{
texts.innerHTML += '<div><input type="radio" name="condition_hits" value="select_money" /> ></div>';
texts.innerHTML += '<div><input type="radio" name="condition_hits" value="select_money1" /> <</div>';
texts.innerHTML += '<div><input type="text" name="input_hits"' + '" value="select_hits" /></div>';
}
if (val == "time_founded")
{
texts.innerHTML += '<div><input type="radio" name="condition_time" value="select_money" /> before date </div>';
texts.innerHTML += '<div><input type="radio" name="condition_time" value="select_money1" /> after date</div>';
texts.innerHTML += '<div><input type="text" name="input_time"' + '" value="select_date" /></div>';
}
}
}
var print = function()
{
var category = document.droplist.select.value;
document.getElementById("category").innerHTML = category
}
</script>
<body>
<form name="droplist" action="html_form_action.asp" method = "get">
<select id="select" size="1">
<option value=" " selected="selected"> </option>
<option value="employees">Number of Employees</option>
<option value="hits">Hits on TechCrunch</option>
<option value="time_founded">Time Founded</option>
<option value="total_money">Total Money</option>
</select>
<hr/>
<div id="texts"></div>
<input type="button" value="Submit" onClick="print()"/>
</form>
<div id="category"></div>
</body>
I tried to do this by using “//var realValue = document.getElementByName(‘input_employees’)[0].value;” but this is clearly not working. I would also like to know how to then pass on this information as a paramater for a function in my python app.
Thanks!
Might I suggest the following:
<div>s in your javascript. You can write to the<div>‘s innerHTML.I unfortunately cannot comment on the question, so I had to post here. Sorry about that.
