i am working in D3..based on the input i want to fetch data from the database to D3..when i type some word in the input field and click submit it works fine...there is no problem in D3...but when i change the input field there is no action in the submit button..it want me to refresh to search for the new word...is anything wrong in the way i use the ajax here..
$(function (all) {
$('form').on('submit', function (e) {
e.preventDefault();
var t=$('form').serialize();
var u='http://localhost:8888/saff/indexi.php?'+t;
$.ajax({
url:u,
async:true,
success:function(data){
funn();
}
});
function funn(){
d3.json(u, function(treeData) {
//d3 code
});
}
});
});
secondly,when i change the form input as
<form name="editorForm" id="formi">
<input type="text" name="editor"
id="editor" onchange="document.getElementById('formi').submit();"/>
<input type="submit"value="butn">
<br />
</form>
type word in the field and submit only making changes in the url as http://localhost:8888/saff/keyy.html to http://localhost:8888/saff/keyy.html?editor=அகடம் and nothing displayed in the webpage how should i use ajax in d3 to get the data from php to d3 based on input,without page refresh
THE Problem is *WHEN THE SUBMIT FIRST WORD IT GET CORRECT DESIGN IN WEBPAGE *WHEN I CHANGE THE INPUT TEXT,THE SECOND DESIGN COMES BELOW THE FIRST DESIGN why ajax is not working??? UPDATE my complete code

finally there is no path error in the console but on input change the d3 design shows below the first input design any idea?why ajax is not working here?
$('form').find(':submit').on('click', function() {
var t = $('form').serialize();
var u = 'http://localhost:8888/saff/indexi.php?' + t;
$.ajax({
url: u,
async: true,
success: function(data) {
funn(data);
}
});
function funn(treeData) {
d3.json(u, function(error, treeData) {
//d3 code
});
}
return false;
});
