jQuery.inArray总是返回-1

Question

我有以下购物清单

我希望每次用户点击垃圾箱都可以从列表中删除产品。 所以我有这个：

  $(document).ready(function() {

var selectedproducts = new Array(); //List of selected products



$("#add_product_button").button();
$("#add_product_button").click(function() {


  //Add some products to selectedproducts
      //Omitted for clarity
selectedproducts[i]=document.getElementById("autocomplete_text_field").value;
         thesi=jQuery.inArray(document.getElementById("autocomplete_text_field").value,selectedproducts);  
         var row=$('<div class"productsclass" style="height:50px; background-color:#E36D84; -webkit-border-radius: 5px; border-radius: 5px; border-style:solid; border-color:#DB4865; id='+rowID+'" ><label style="position:relative; top:10px; left:2px; font-size:20px">'+selectedproducts[i]+'</label><input  style="position:relative; left:2px; top:10px; width:20px;" type="text" name="Quantity" value="1"><img class="delete" id="'+rowID+'" src="http://b.dryicons.com/images/icon_sets/handy_part_2_icons/png/128x128/recycle_bin.png" height="22"  width="22" style="position:relative; top:10px; float: right;"></div><br>'); 
       rowID++;
       $("#productstable").append(row);
       i++;
       console.log("Thesi: "+thesi+" Timi:"+document.getElementById(thesi).value);

});



 //Delete products
$(document).on("click", "[class*='delete']", function(s) {

    thisID = $(this).attr('id'); //find items parent
    console.log("ThisID: "+thisID);
    console.log(jQuery.inArray(thisID,selectedproducts));//find item's position in the selectedproducts
    selectedproducts.splice(thisID,1);
    $(this).parent().hide("explode", 1000);
    $(this).parent().remove();//delete item
    console.log("Size:"+selectedproducts.length);
    console.log(selectedproducts);


}); 


});

问题是jQuery.inArray总是返回-1。从UI中删除正确的产品，但是从selectedproducts Array

中删除

HTML：

  <div id="maindiv" class="maindiv">
<input id="autocomplete_text_field">
<button id="add_product_button">Add product</button>
</div>

<div id="supplier">
<form name="frm1" action="http://localhost/tddd27/index.php/auth/session">
<input type="image" src="<?php echo base_url()?>assets/images/fb_supplier.png" />
</form>
</div>


<div id="ProductsDiv" class="ProductsDiv" hidden="true">
<div id="tabs">
  <ul>
    <li><a href="#fragment-1"><span>Shopping List</span></a></li>
  </ul>
  <div id="fragment-1">
 <form action="#" id="productstable" name="productstable">
<p></p>
</form>
</div>
  </div>
</div>

知道我的问题是什么吗？

Answer 1

你的要求

thesi=jQuery.inArray(thisID,selectedproducts);

但是

selectedproducts

未定义。或者我错过了什么？
