call jquery function from javascript not working
I read similar posts on this but fails to work at this time. Mine is slightly different.
I call a javascript function addFormField which creates a dynamic input element within a form. This part works fine. Within that function I call the JQuery function loadData(id) to test if the id of the dynamically created element exists but it does not. Is loadData being called correctly to wait $ for the input element id to be created before checking if it's created? Thanks!
function addFormField() {
var id = document.getElementById("id").value;
$("#divTxt").append("<p id='row" + id + "'><label for='txt" + id + "'>Field " + id + " <input type='text' size='20' id='txt" + id开发者_JAVA百科 + "'><p>");
$(function () {
loadData(id);
});
id = (id - 1) + 2;
document.getElementById("id").value = id;
}
function loadData(id) {
if ( $('#txt' + id).length ){
alert('success');
}
else {
alert ('fail');
}
}
<html>
<p><a href="#" onClick="addFormField(); return false;">Add</a></p>
<form method="get" id="form1" action='#'>
<input type="hidden" id="id" value="1">
<div id="divTxt"></div>
</html>
Your code works fine for me: http://jsfiddle.net/6t8eX/
Just make sure that the addFormField() method is global. If it isn't, the inline onClick won't be able to find it.
If it is wrapped in $(function () { }), (or in any other function body) it won't be global.
