本章演示如何根据数据库构建输入表单。
本页上的示例使用本地 SQL 数据库。
本地 SQL 数据库不适用于 IE 或 Firefox。使用 Chrome 或 Safari。
{
"database" : {
"connection" : "localmysql",
"maintable" : "Customers",
"keyfield" : "CustomerID",
"sql" : "SELECT * FROM Customers"},
"updateItems" : [
{"item" : "CustomerName"},
{"item" : "Address"},
{"item" : "PostalCode"},
{"item" : "City"},
{"item" : "Country"}]
}
在上一章中,您创建了一个用于列出数据库中的记录的应用程序。
现在向页面添加一个表单应用程序:
<div id="Form01" class="w3-container w3-light-grey w3-padding-large w3-margin-bottom" appml-data="local?model=model_customersform">
<p>
<label for="customername">Customer:</label>
<input id="customername" class="w3-input w3-border">
</p>
<p>
<label for="address">Address:</label>
<input id="address" class="w3-input w3-border">
</p>
<p>
<label for="city">City:</label>
<input id="city" class="w3-input w3-border">
</p>
<p>
<label for="postalcode">Postal Code:</label>
<input id="postalcode" class="w3-input w3-border">
</p>
<p>
<label for="country">Country:</label>
<input id="country" class="w3-input w3-border">
</p>
</div>

appml-data="local?model=model_customersform"定义表单的 AppML 应用程序。
使用您最喜欢的样式表(我们使用Bootstrap),并创建您想要的表单命令:
<span onclick="document.getElementById('Form01').style.display='none'" class="w3-button w3-xlarge w3-right">×</span>
<div class="w3-bar w3-border w3-white">
<button onclick="appml('Form01').newRecord();" class="w3-btn">New</button>
<button onclick="appml('Form01').saveRecord();" class="w3-btn w3-green">Save</button>
<button onclick="appml('Form01').deleteRecord();" class="w3-btn">Delete</button>
</div>
<div id="appmlmessage" class="w3-container w3-pale-yellow w3-padding" style="display:none;">
<span onclick="this.parentNode.style.display='none';" class="w3-button w3-xlarge w3-right">×</span>
<div id="message"></div>
</div>
在表单中包含表单命令:
<div id="Form01" class="w3-container w3-light-grey w3-padding-large w3-margin-bottom" appml-data="local?model=model_customersform">
<div appml-include-html="inc_formcommands.htm"></div>
<p>
<label for="customername">Customer:</label>
<input id="customername" class="w3-input w3-border">
</p>
<p>
<label for="address">Address:</label>
<input id="address" class="w3-input w3-border">
</p>
<p>
<label for="city">City:</label>
<input id="city" class="w3-input w3-border">
</p>
<p>
<label for="postalcode">Postal Code:</label>
<input id="postalcode" class="w3-input w3-border">
</p>
<p>
<label for="country">Country:</label>
<input id="country" class="w3-input w3-border">
</p>
</div>

在上一章中,您创建了一个用于列出数据库中的记录的应用程序。
现在向表中添加一个新列:
<div appml-data="local?model=model_customerslist">
<h1>Customers</h1>
<div appml-include-html="inc_listcommands.htm"></div>
<div appml-include-html="inc_filter.htm"></div>
<table class="w3-table-all">
<tr>
<th></th>
<th>Customer</th>
<th>City</th>
<th>Country</th>
</tr>
<tr appml-repeat="records">
<td style="cursor:pointer;width:34px;" onclick="appml('Form01').run({{CustomerID}})">✎</td>
<td>{{CustomerName}}</td>
<td>{{City}}</td>
<td>{{Country}}</td>
</tr>
</table>
</div>
亲自试一试»
onclick 事件(在新列中)触发调用以运行位于 id="Form01" 的 HTML 元素中的 AppML 应用程序:
向表单添加样式以使其不可见:
<div id="Form01" appml-data="local?model=model_customersform"
appml-controller="myFormController"
class="jumbotron"
style="display:none">
向表单添加一个控制器,仅在表单加载并准备好显示数据时显示表单:
<script>
function myFormController($appml) {
if ($appml.message == "ready") {return -1;}
if ($appml.message == "loaded") {
document.getElementById("Form01").style.display="";
}
}
</script>
