Question

I am trying to add text into a hidden text box in the div below when a use clicks delete…

Html

<div class="documentRow">    
<div class="documentHeader">
    <b>Title:</b> 
     <input data-val="true" data-val-required="Required" id="EventDocuments_1__Title" name="EventDocuments[1].Title" style="width:100px" type="text" value="test.doc">   
</div>
<div class="documentDelete">
    <input data-val="true" data-val-required="The Delete field is required." id="EventDocuments_1__Delete" name="EventDocuments[1].Delete" type="hidden" value="False">
</div>
<div class="deleteDoc">
     <button class="button delDocButton ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" role="button" aria-disabled="false"><span class="ui-button-text">Delete</span></button>
</div>

Jquery:

$(".delDocButton").click(function() {
        $(this).parent().parent().toggle();
        $(this).parent().find(".documentDelete input").val("True");  
        return false;
    });

i have several of these “rows” on the page, so i cant reference the text box by id.

Answer 1

the problem is this line:

$(this).parent().find(".documentDelete input").val("True");  

$(this).parent() is the direct parent of the button (<div class="deleteDoc">), and your hidden field is not in there so it wont find it.

To save having to repeat the calls to parent() I suggest sometihng likethis:

$(".delDocButton").click(function() {
    var $container = $(this).parent().parent();
    $container.toggle();  
    $(".documentDelete input",$container).val("True");  
    return false;
});
