Sencha - 使用按钮添加新表单字段 Sencha 表单 - 用户激活
好吧，我可能在这里遗漏了一些基本的东西，但我想看看是否有人能发现这里出了什么问题。我的目标是让用户能够通过单击基于 Sencha 的表单中的按钮来添加新成分（通过食谱表单中的新文本字段）。
另外，文本字段名称（要提交的）需要加 1，以便提交到 MySQL 数据库正常工作，即成分 2、成分 3 ...这是我到目前为止所拥有的（没有模型），另请注意，我已经硬编码字段 bu 出于测试目的隐藏了它们：
var formBase = {
scroll: 'vertical',
url : 'server.php',
standardSubmit : false,
items: [
{
xtype: 'fieldset',
title: 'Add Recipe',
ref: 'fs',
//instructions: 'Please enter the information above.',
defaults: {
required: true,
labelAlign: 'left',
labelWidth: '40%',
},
items: [
{
xtype: 'textfield',
name : 'name',
label: 'Recipe Name',
useClearIcon: true,
autoCapitalize : false
},
{
xtype: 'textfield',
name : 'ingredients',
label: 'Ingredients',
useClearIcon: true,
autoCapitalize : false
},
{
xtype: 'textfield',
name : 'ingredients2',
label: 'Ingredients 2',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients3',
label: 'Ingredients 3',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients4',
label: 'Ingredients 4',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients5',
label: 'Ingredients 5',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients6',
label: 'Ingredients 6',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients7',
label: 'Ingredients 7',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients8',
label: 'Ingredients 8',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients9',
label: 'Ingredients 9',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textareafield',
name : 'comments',
label: 'Comments',
maxLength: 50,
maxRows: 5,
height: 120
},
{
xtype: 'emailfield',
name : 'email',
label: 'Email',
placeHolder: '[email protected]',
useClearIcon: true
},
{
xtype:'button',
text: 'Add Ingredient',
handler: function() {
var p = formBase.fs.items.items + 1;
formBase.fs.insert(p, {
xtype: 'textfield',
name : 'ingredients',
label: 'Added field'
});
formBase.fs.doLayout();
}},
]
}
],
我收到的错误是：未捕获的类型错误：无法读取未定义的属性“项目”
感谢您的所有帮助！ - BRR
Ok, I'm probably missing something basic here but I wanted to see if someone can catch what is going wrong here. My goal is to have the user be able to add a new ingredient (via new textfield in my recipe form) by clicking a button in the Sencha-based form.
Also the textfield name (to be submitted) needs to be incremented by 1 so the submission to the MySQL database works properly, i.e. ingredients2, ingredients3 ...here is what I have so far (without the model), Also notice I have hardcoded the fields bu have hidden them for testing purposes:
var formBase = {
scroll: 'vertical',
url : 'server.php',
standardSubmit : false,
items: [
{
xtype: 'fieldset',
title: 'Add Recipe',
ref: 'fs',
//instructions: 'Please enter the information above.',
defaults: {
required: true,
labelAlign: 'left',
labelWidth: '40%',
},
items: [
{
xtype: 'textfield',
name : 'name',
label: 'Recipe Name',
useClearIcon: true,
autoCapitalize : false
},
{
xtype: 'textfield',
name : 'ingredients',
label: 'Ingredients',
useClearIcon: true,
autoCapitalize : false
},
{
xtype: 'textfield',
name : 'ingredients2',
label: 'Ingredients 2',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients3',
label: 'Ingredients 3',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients4',
label: 'Ingredients 4',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients5',
label: 'Ingredients 5',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients6',
label: 'Ingredients 6',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients7',
label: 'Ingredients 7',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients8',
label: 'Ingredients 8',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textfield',
name : 'ingredients9',
label: 'Ingredients 9',
useClearIcon: true,
autoCapitalize : false,
hidden: true
},
{
xtype: 'textareafield',
name : 'comments',
label: 'Comments',
maxLength: 50,
maxRows: 5,
height: 120
},
{
xtype: 'emailfield',
name : 'email',
label: 'Email',
placeHolder: '[email protected]',
useClearIcon: true
},
{
xtype:'button',
text: 'Add Ingredient',
handler: function() {
var p = formBase.fs.items.items + 1;
formBase.fs.insert(p, {
xtype: 'textfield',
name : 'ingredients',
label: 'Added field'
});
formBase.fs.doLayout();
}},
]
}
],
The error I am receiving is: Uncaught TypeError: Cannot read property 'items' of undefined
Thanks for any and all help! - BRR

labelWidth 之后的逗号会破坏它，不是吗？
That comma after labelWidth would break it wouldn't it?
在线p= formBase.fs.items.items + 1;
字段 fs 没有定义为 formBase 变量的属性，因此它没有被解析（因此它是未定义的）。因此，当尝试引用“fs”中的“items”时，您会收到错误。 （您试图引用 fs 中的项目，而 fs 未定义）。
On the line p= formBase.fs.items.items + 1;
The field fs is not defined as a property on the formBase variable, so it is not being resolved (thus it is undefined). Therefore when attempting to reference 'items' within 'fs' you are getting an error. (you are attempting to reference items within fs, and fs is undefined).
