问题 I'm trying to submit a form to a website not my own (salesforce.com with their web-to-lead function) and I'm doing it through a javascript modal window. Basically once all the entries are tested and made sure there are no errors, I use this: if(error_count == 0) { $.ajax({ type: "POST", url: "[salesforce url]", data: "first_name=" + first_name + "&last_name=" + last_name + "&email=" + email + "&firm=" + firm + "&[salesforceid]=" + AUM + "&[salesforceid]=" + custodian + "&[salesforceid]=" +

问题 I'm implementing a typical shopping cart, based on PrimeFaces' dataGrid component. Below is some sample code. Everything is ok, but the inputText field causes the bean property to be set as many times as there are elements in the page. So, if I put 1 in the first item in the datagrid, it is set, but it's set to 0 N times after this, thus overwriting it. I guess this is because each inputText has the same id. I have tried to enclose the input + commandLink within their own form, but that doesn

问题 In Symfony v3.2, I'm using a form with several EntityType fields, which have hundreds of options - and each option is a relatively big object. Since they don't change so often, I'd like to use some Cache in Symfony, to load them once and just keep feeding the EntityType with it. I've already cut down the size of the data that's feeding it, by pulling just the fields that I need, and then saved that into a cache. When I pull the data from cache - I cannot feed it directly to EntityType with a

问题 I am creating a non-model object that will be used with a Rails form builder by using ActiveModel . This is a Rails 3 project. Here's an example of what I have so far: class SalesReport include ActiveModel::Validations include ActiveModel::Conversion extend ActiveModel::Naming attr_accessor :promotion_code, :start_date, :end_date def initialize(attributes = {}) attributes.each do |name, value| send("#{name}=", value) end end def persisted? false end end I happen to be using HAML and simple

问题 I am trying to learn how to use the Acts as Taggable On gem with Rails 5. I use simple form for forms. I think part of the problem arises out of there not being an association on the models between proposal and randd_fields. I have models called Proposal and Randd::Field. I am trying to tag proposals with tags which are the :title attribute of the Randd::Field table. My models have: Proposal class Proposal < ApplicationRecord acts_as_taggable_on :randd_maturities, :randd_fields, :randd

问题 I'm working on a web project that has a lot of abstraction - lots of code is squirreled away in view templates, internal company javascript libraries, etc. I have been asked to "hijack" the form submit buttons to disable them when the form is submitted, to disallow extra clicks. The problem is, I still have to submit the button as it's used in 99% of our system as a form input (not best practices, but I didn't write that code!) What I have done is when the user clicks "Save," that button is
