Question

我想在输入类型中删除onclcik之后存储的值。现在我想删除值onclick。如果取消选中添加值的框，我使用复选框添加条件值。现在我想在检查条件下从输入onclick中删除匹配的值，如果是。

            </div>
         </div>
      </div>
   </li>
</ul>

的Javascript

var numArray = [];

function handleClick(cb) {

    if (jQuery('related-products-field')) {

        if (jQuery('related-products-field')) {

            var checkbox = jQuery('#related-checkbox-' + cb);
            // The is(':checked') function checks if the checkbox is checked
            var isChecked = checkbox.is(':checked');
            if (isChecked) {

                I want remove code here
            }
        }
        if (!isChecked) {

            numArray.push(cb);
            //alert(numArray);
            //var allele = document.getElementById("dialog").innerHTML = numArray;
            document.getElementById('related-products-field').value = numArray.join(",");

        }

        //alert("xcccc");

        checkbox.prop('checked', !isChecked);


        // do the rest of the function
    }

}
// }
}

值保存在点击

的输入中

 <input type="hidden" name="related_product" id="related-products-field" value="338,339,340">

Answer 1

if (isChecked) { var index = numArray.indexOf(cb); //to get index of your item in numArray if (index > -1) { numArray.splice(index, 1); //removes item from array } document.getElementById('related-products-field').value = numArray.join(",") }

javascript有splice()函数从数组中删除项目。
