如何使用jQuery获取动态表的输入字段值

Question

I'm currently using Meteor/Blaze framework to build a table. The row in the table will change according to the selected supplier. I have added class={{_id}} to the field and q.{{_id}} , lot.{{_id}} , and exp.{{_id}} to the quantity, lot , and expire date INPUT .

I'm trying to write a Submit Events to get these value and pass it to the Mongo Database. Please suggest a good way to loop through these rows to get the value.

receiveRow2 template

<template name="receiveRow2">
  <tr id="{{_id}}">
    <td class="pn">{{name}}</td>
    <td class="pq">{{totalQuantity}}</td>
    <td>{{uomid.name}} ({{uomid.unit}} {{uomid.unitname}}/{{uomid.name}})</td>
    <td><input type="text" class="form-control" name="q.{{_id}}" placeholder="Quantity" /></td>

</template>

JS

Template.receiveForm.events({
  'submit form': function(event, template){
    var supplierSelected = Template.instance().supplierSelected;
    items = Products.find({suppliers: supplierSelected.get()});
    event.preventDefault();
    docdate = event.target.docdate.value;
    supplier = event.target.supplier_sel.value;
    console.log("---event---");
    console.log(docdate)
    console.log(supplier)
    items.forEach(function(item){
      ????
    })
  }
})

Answer 1

In line 4 its missing a var before items, and also in line 6, 7.

After that I think you can loop on them.(But they will come from the DB).

BUT if you want to get the input values, why would you ask for a data in MongoDB? Also I would prefer to get DB values as a promise.

var items = Promise.resolve(Products.find({suppliers: supplierSelected.get()});

and get back the items in this way:

items.then(function(item){console.log(item)})
