Custom dialog window with search function and customfields

[Oleksii Okhmush]

Hello everyone!

I try to create custom dialog where i want to use IssuePicker custom field, and after selecting issue with this custom field show some customvields value from picked field

Using scriptrunner i created Web-fragment to initiate REST endpoint:

my.domain.siterest/scriptrunner/latest/custom/showDialog

My REST endpoint shows dialog window

import com.onresolve.scriptrunner.runner.rest.common.CustomEndpointDelegate
import groovy.transform.BaseScript
import javax.ws.rs.core.MediaType
import javax.ws.rs.core.MultivaluedMap
import javax.ws.rs.core.Response
@BaseScript CustomEndpointDelegate delegate

showDomain() { MultivaluedMap queryParams ->
def dialog =

"""<section role="dialog" id="sr-dialog" class="aui-layer aui-dialog2 aui-dialog2-large" aria-hidden="true" data-aui-remove-on-hide="true">
<header class="aui-dialog2-header">
<h2 class="aui-dialog2-header-main">Domain Lookup</h2>
<a class="aui-dialog2-header-close">
<span class="aui-icon aui-icon-large aui-iconfont-close-dialog">Close</span>
</a>
</header>
<div class="aui-dialog2-content">
<p><b>Enter domain: </b>
<form class="aui" action="#">
<input id="domain-search" class="text" type="search" name="domain">
<button class="aui-button ">Search</button>
</form>


<br> <hr>





</div>

<footer class="aui-dialog2-footer">
<div class="aui-dialog2-footer-actions">
<button id="dialog-close-button" class="aui-button aui-button-link">Ok</button>
</div>


<div class="aui-dialog2-footer-hint">Hint for use </div>

</footer>
</section>

"""
Response.ok().type(MediaType.TEXT_HTML).entity(dialog.toString()).build() 
}

Is it possible to use IssuePicker customfield in <input> section

Or if its not possible, enter some text in this <input> and them search using JQL with this input and shows information in this dialog window?
