I have multiple anchor tag generated by php from database like this
<a href="#" id="reply_doc" data-doc_value="1"></a>
<a href="#" id="reply_doc" data-doc_value="2"></a>
<a href="#" id="reply_doc" data-doc_value="3"></a>
Now I got JQuery script
$(document).ready(function(){
$("#reply_doc").click(function () {
var a = $(this).data("doc_value");
if (a != "") {
$.ajax({
type: "POST",
url: "ajax_check/",
data: "doc_reply=" + a,
success: function (b) {
alert(a+' ok. '+b)
}
});
}
});
});
This is only applying for the first anchor tag. How can I do this for each anchor tag when that particular is clicked only that anchor will be affected and that particular value will be send with ajax.
Any help will be appreciated. thanks in advance.
The id
attribute is an identifier . As the name might suggest, that means it has to be unique so that it can identify a single element. In order to recognise multiple elements, you'll need to use a class instead:
<a href="#" class="reply_doc" data-doc_value="1"></a>
<a href="#" class="reply_doc" data-doc_value="2"></a>
<a href="#" class="reply_doc" data-doc_value="3"></a>
$(".reply_doc").click(...);
Change the id
to a class
, and change your selector to ".reply_doc"
.
Your html is currently invalid because the id
attribute should be unique. Although the browser doesn't jump up and down complaining when you break this rule, when you try to select an element by id
it only finds the first (or, in some browsers, the last).
If, hypothetically, you have no control over the html structure you could instead select all anchor elements with the data-doc_value
attribute:
$("a[data-doc_value]")...
Elements cannot have same id so bind event on same class .
a href="#" class="option" id="reply_doc" data-doc_value="1"></a>
<a href="#" class="option" id="reply_doc" data-doc_value="2"></a>
<a href="#" id="reply_doc" class="option" data-doc_value="3"></a>
JQuery script
$(document).ready(function(){
$(".option").click(function () {
var a = $(this).data("doc_value");
if (a != "") {
$.ajax({
type: "POST",
url: "ajax_check/",
data: "doc_reply=" + a,
success: function (b) {
alert(a+' ok. '+b)
}
});
}
});
});
Edited again DEMO
<a href="#" class="reply_doc" data-doc_value="1">111</a><br>
<a href="#" class="reply_doc" data-doc_value="2">222</a><br>
<a href="#" class="reply_doc" data-doc_value="3">333</a><br>
$(document).ready(function(){
$(".reply_doc").click(function () {
var a = $("a.reply_doc").attr("data-doc_value"); //<-- Add this
if (a != "") {
$.ajax({
type: "POST",
url: "ajax_check/",
data: "doc_reply=" + a,
success: function (b) {
alert(a+' ok. '+b)
}
});
}
});
});
This way each time " a " will have unique value contained in data-doc_value on click
