onClick-从另一个文件调用功能

Question

我有一个链接到前端的functional.js文件，在这里我要单击div（item1wrapper）并从index.js文件中调用一个函数。

在这个functional.js文件中，我附加了div：

  socket.on('response', function (data) {
        if (msg.includes('totalPrice')) {    
        if (parsed.itemPrice.length === 1) {
            $('#messages').append($('<li id="messageclient">').append($(`
            <div id="message-cont" class="message-cont">     
            <div class="orderDetailsWrapper">
            <div class="detailsHeaderWrapper">
                <div class="orderNum"></div>
                <div class="customerName"></div>
            </div>

            <div class="textToCustomer">
            <p> Please click on the item you want to return</p>

           </div>

           <div class="itemBoxWrapper">
           <div id ="item1Wrapper" class="item1Wrapper" onclick="">
               <div class="item1Title"></div>
               <div class="item1Price"></div>
           </div>`
        )).append($('<div id="client-imgorder">')));
        $("#messages").animate({ scrollTop: $("#messages")[0].scrollHeight }, 1000);

        $('.customerName').text('Customer name: ' + customerName);
        $('.orderNum').text('Order number: ' + orderNum);

        $('.item1Title').text('Item: ' + item1Title);
        $('.item1Price').text('Price: ' + item1Price);

        }

模块导出无法正常工作，因为它已链接到前端？

这是我的index.js文件中的函数：

 function oneCall() {
            itemId = itemIdArray[0];
            // matching API get 

            // getRefundCalc API post.
            console.log('ngrokurl' + ngrokUrl)
            console.log('domain' + domain)
            console.log('orderId' + orderId)
            console.log('itemId' + itemId)

            /*
            The Purchase date must be in the future
            */


            rp(optionsPOST1)
                .then(function (parsedBody) {
                    Match = parsedBody.Match;
                    if (Match) {
                        console.log('Match is true');

                        httpRequest.post(
                            `${ngrokUrl}/${domain}/${orderId}`,
                            {
                                json:
                                    {
                                        "line_items": [
                                            {
                                                "line_item_id": itemId, "quantity": 1
                                            }
                                        ]
                                    }
                            },
                            function (error, resp, body) {
                                if (!error && resp.statusCode == 200) {
                                    console.log(body)

                                    response = responseToFrontEnd
                                    data = [details.chatuser, response]
                                    io.of('/main').to(socket.id).emit('response', data);

                                }
                                else {
                                    console.log('error' + error)
                                }
                            }
                        )
                        // include getRefundCalc within here
                    } else {
                        console.log('Match is false');
                        response = `I'm sorry but your item fell out of the refund policy. Please check the purchase date of your item or if it falls under the minimum price.`
                    }
                });
            }

当前，“ onclick”为空，因为它无法正常工作，当我在那个functional.js文件中单击该div时，我想调用该函数！而且它必须在功能文件之外，因为它需要节点模块，并且必须在套接字函数中！
