<body>
<input type="text" id="name">
<input type="button" onclick="call(id_of_input_type_text)" value="Click

<script>
var call(id_of_input_type_text) = function(){

Option 1 (from your question):
Note you can use call('name') in this case.
var call = function(id){
var x = document.getElementById(id).value;
alert(x);
}<input type="text" id="name">
<input type="button" onclick="call(document.getElementById('name').id)" value="Click me">Option 2 (send the element, so you won't need to get it in the function):
var call = function(elem){
var x = elem.value;
alert(x);
}<input type="text" id="name">
<input type="button" onclick="call(document.getElementById('name'))" value="Click me">

Use the same function with different arguments for each call. Like you can use:
<input type="button" onclick="call('name')" value="Click Me">
And it will alert the value of input field with id 'name'.
Hope this helps.

You can use the below code as reference:
<body>
<input type="text" id="name">
<input type="button" onClick="call('name')" value="Click me" id="btnOne">
<script type="text/javascript">
var call = function(elementId)
{
var valueOfInput = document.getElementById(elementId).value
alert(valueOfInput);
}
</script>
</body>
