I have a Javascript function for creating new form elements on a web page. The function is called by an onclick event.
I can't figure out how to run the function without the onclick event. I need to do this as I have Python code generating content to prepopulate the form elements, but still wish to be able add and remove the form elements dynamically with the Javascript.
Javascript function:
pcount = 0; createinputprice =function (){ field_area = document.getElementById('pricetable'); var tr = document.createElement("tr"); var cella = document.createElement("td"); var cellb = document.createElement("td"); var input = document.createElement("input"); var input2 = document.createElement("input"); input.id = 'descprice'+pcount; input2.id = 'actprice'+pcount; input.name = 'descprice'+pcount; input2.name = 'actprice'+pcount; input.type = "text"; input2.type = "text"; cella.appendChild(input); cellb.appendChild(input2); tr.appendChild(cella); tr.appendChild(cellb); field_area.appendChild(tr); //create the removal link var removalLink = document.createElement('a'); removalLink.onclick = function(){ this.parentNode.parentNode.removeChild(this.parentNode) } var removalText = document.createTextNode('Remove Field'); removalLink.appendChild(removalText); tr.appendChild(removalLink); pcount++ } HTML:
<table> </table> <a href='#' onclick="createinputprice()">Add Price</a> <script type="text/javascript"> createinputprice(); </script> The onclick event works fine in JSFiddle but calling the function directly doesn't work at all.

you can put it into tag using 'onload' event:
<body onload='yourfunction()'> or just use jQuery:
$(document).ready(function() { yourFunc(); }); I suppose you could use <body onload="yourfunction()"> you also should look into .
As you can see there are quite a few events available in javascript one should allways pick the right tool(event) for doing the work.
If you want to call jquery function on Page load: you can use $(document).ready(function(){});
For example:
Jquery-
<script type="text/javascript"> $(document).ready(function(){ createinputprice(); }); </script> and you can also fire the click event in Jquery:
HTML-
<a href='#' onclick="createinputprice();">Add Price</a> Jquery-
<script type="text/javascript"> $(document).ready(function(){ $('#myLink').click(); }); </script>
