I have these text fields.
<input type="text" value="<p>aaaaaaaaaaa</p>" id="tab_4_0_li_div_content"><input type="text" value="lab" id="tab_4_0_li_data"><input type="text" value="<p>dddd</p>" id="tab_4_1_li_div_content"><input type="text" value="client" id="tab_4_1_li_data">
Here tab_4_*_li_data
is a <li>
html of tab , and tab_4_0_li_div_content
is id
of <div>
which will be show on <li>
click.
Now I want to extract data from this input fields using regular expression. For example
client,lab
as key and
<p>aaaaaaaaaaa</p>,<p>dddd</p>
as value of key.
If you see these are related to each others.
tab_4_0_li_div_content tab_4_0_li_data
<p>aaaaaaaaaaa</p> lab
tab_4_1_li_div_content tab_4_1_li_data
<p>dddd</p> client
Div content part can content any thing, It's an text area. So how we do this?
There is no reason to have to use a regular expression to parse HTML. One thing, you are not going to have a good time going it. Second, use the power of the DOM
var contents = $("[id$=content]"); //find the elements that have an id that end with content var datas = $("[id$=data]"); //find the elements that have an id that end with data var details = {}; //object to hold results datas.each( function(i) { details[datas[i].value] = contents[i].value; }); //start looping and generate the object with the details you are after console.log(details); //Object {lab: "<p>aaaaaaaaaaa</p>", client: "<p>dddd</p>"}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <input type="text" value="<p>aaaaaaaaaaa</p>" id="tab_4_0_li_div_content"><input type="text" value="lab" id="tab_4_0_li_data"><input type="text" value="<p>dddd</p>" id="tab_4_1_li_div_content"><input type="text" value="client" id="tab_4_1_li_data">
Now that code assumes the data and content elements are in the same order, if not, than it would require a little processing, but it is not that hard to do.
var datas = $("[id$=data]"); var details = {}; datas.each(function(i, elem) { var id = elem.id; var val = $("#" + id.replace("data", "div_content")).val(); details[elem.value] = val; }); console.log(details); //Object {lab: "<p>aaaaaaaaaaa</p>", client: "<p>dddd</p>"}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <input type="text" value="<p>aaaaaaaaaaa</p>" id="tab_4_0_li_div_content"> <input type="text" value="lab" id="tab_4_0_li_data"> <input type="text" value="<p>dddd</p>" id="tab_4_1_li_div_content"> <input type="text" value="client" id="tab_4_1_li_data">
You can do it like this:
function getValuesById(id1,id2){
var vals = {};
if(id1 === undefined)
id1 = "\\d+";
if(id2 === undefined)
id2 = "\\d+";
$("input").each(function (index, value) {
console.log(new RegExp('tab_(' + id1 + '_' + id2 + ')_li_data'));
var match = value.id.match(new RegExp('tab_(' + id1 + '_' + id2 + ')_li_data'));
if (match) {
vals[value.value] = $("#tab_" + match[1] + "_li_div_content").val();
}
});
return vals;
}
Here I search through all input fields and match against tab_DIGITS_DIGITS_li_div_data
and put that as a key and corresponding li_div_content as value in object values.

UPDATE: I have updated the code to a function where you can send in a parameter to your two numerical values and will use any number if not supplied, ie use as getValuesById(4)
for values like tab_4_*_li
