It is often required to be able to access Document property Control values (Input/drop-down/List-box, etc.) that are part of the Text Area from the JavaScript/JQuery associated with any given HTML Text Area. Since the JavaScript that has been added to the HTML Text Area is a client-side programming language, it does not have access to the Spotfire Document model framework. Use the approach described in the following example to fetch the values.
 

How to access Text Area Document Property control values using Java Script/JQuery.

Consider the following sample HTML.

    <!-- Input -->
    <p><SpotfireControl id="23ed572641844696af84ed1e0721a2c7" /></p>
    <!-- Label -->
    <p><SpotfireControl id="c16bb15d571f4cba897c033ef44a5c5a" /></p>
    <!-- Dropdown -->
    <p><SpotfireControl id="c3dace8ed60e47b2a0b6d59cc6c5d021" /></p>
    <!-- ListBox -->
    <p><SpotfireControl id="202f94483ee142a6b604c25d452b221a" /></p>

The following is how to access the values from each of the controls.

    //For an input:
    var inputVal = $("#23ed572641844696af84ed1e0721a2c7")[0].value
    //alert('Input >> ' + inputVal)

    //For Label
    var labelVal = $("#c16bb15d571f4cba897c033ef44a5c5a").text()
    //alert('Label >> ' + labelVal)

    //For Drop down
    var dropdownVal = $("#c3dace8ed60e47b2a0b6d59cc6c5d021 :selected").text()
    alert('Drop down >> ' + dropdownVal)

    //For List Box
    var listBoxVal = $("#202f94483ee142a6b604c25d452b221a :selected").text()
    alert('List Box >> ' + listBoxVal)

It is recommended to wrap your property controls with an element, e.g., a div with id='inputWrapper' . You can then get its value. This is because your property control ID may change (mostly in Web Player).

Sample HTML with div wrapper:

    <div id="inputWrapper"><SpotfireControl id="63370b89863146a2b2cde4a3e2db74ae" /> </div>
    <div id="labelWrapper"><SpotfireControl id="f9f5274f68d740c8a441075be38f70a5" /></div>
    <div id="dropDownWrapper"><SpotfireControl id="e2329c55dbc746b0b1c878cd591cafb2" /></div>


Accessing the values from controls with the wrapper ID:

    //For an input:
    var inputVal = $("#inputWrapper > input").first().val()
    //alert('Input >> ' + inputVal)

    //For Label:
    var labelVal = $("#labelWrapper").text()
    //alert('Label >> ' + labelVal)

    //Drop down
    var dropdownVal = $("#dropDownInput .ComboBoxTextDivContainer div").text()
    alert('Drop down >> ' + dropdownVal)
