How to compare two arrays to set html multiselect in jsp
I maintained a list of selected values from an html multiselect in a string array taken from a database. I want to compare the values of these selected options with the full select option list in order to set them as selected on loading the screen. I keep getting multiple instances for the same select options due to the loop.
<select id="selectForm" name="selectForm" multiple="multiple">
<c:forEach items="${FullList}" var="fullList">
<c:forEach items="${PreSelected}" var="preSelected">
<option ${preSelected== fullList.name ? 'selected="selected"' : ''}>${fullList.name}</option>
</c:forEach>
</c:forEach>
</select>
How do I get a single unique select list with the stored values already selected? Is there a better way of solving the problem than my approach?
