html - Jquery查找ID并附加到输入

Question

我有以下html。我想在 span class="form-error" 上找到 ID，并将 ID 包含到输入中的 aria- describeby

    <label class="Name cell medium-6  ">
<span class="field-title">Name*</span>
<div class="searchbar search-form search-tradein">                        
    <searchbox use-suggest="true" hide-suggest-onblur="true" suggest-onfocus="true">                            
        <input id="searchbox2" onclick="searchFocus();" name="122" data-elementid="122" class="related-data-element" data-elementtype="Answer" required="" aria-describedby="">                        
    </searchbox>                                      
</div>
<span class="form-error" id="z6an3x-abide-error" role="alert">Please add Name</span>
</label>
