# 基礎網頁
|
||
### 先看全部程式碼
|
||
``` HTML
|
||
<!--CSS的部分-->
|
||
<style>
|
||
table {
|
||
border-collapse: collapse;
|
||
border-spacing: 0px;
|
||
}
|
||
|
||
table,
|
||
th,
|
||
td {
|
||
padding: 5px;
|
||
border: 1px solid black;
|
||
}
|
||
|
||
</style>
|
||
|
||
<!--HTML的部分-->
|
||
<body>
|
||
<h1>Demo</h1>
|
||
<div>
|
||
<button onclick="button_click()">123</button>
|
||
<br>
|
||
<br>
|
||
<input id="text_in_id"/>
|
||
<button onclick="text_click()">測試按鈕</button>
|
||
<input id="text_out_id"/>
|
||
<br>
|
||
|
||
<br>
|
||
<br>
|
||
<button onclick="alert('這是警告文字');">開啟警告視窗</button>
|
||
<br>
|
||
<br>
|
||
<table>
|
||
<tr>
|
||
<th>First name</th>
|
||
<th>Last name</th>
|
||
</tr>
|
||
<tr>
|
||
<td>John</td>
|
||
<td>Doe</td>
|
||
</tr>
|
||
<tr>
|
||
<td>Jane</td>
|
||
<td>Doe</td>
|
||
</tr>
|
||
</table>
|
||
</div>
|
||
|
||
|
||
</body>
|
||
|
||
<!--JS的部分-->
|
||
<script>
|
||
function button_click() {
|
||
console.log('button_click_確認')
|
||
}
|
||
</script>
|
||
|
||
|
||
|
||
<script>
|
||
function text_click() {
|
||
var in_text = document.getElementById("text_in_id").value
|
||
console.log(in_text)
|
||
document.getElementById('text_out_id').value = in_text
|
||
}
|
||
</script>
|
||
```
|
||
|
||
|
||
### 按鈕
|
||
#### 當123這個按鈕觸發後，會呼叫到button_click這個function，按f12即可看到console的參數
|
||
``` HTML
|
||
<!--HTML-->
|
||
<button onclick="button_click()">123</button>
|
||
|
||
<!--JS-->
|
||
<script>
|
||
function button_click() {
|
||
console.log('button_click_確認')
|
||
}
|
||
</script>
|
||
```
|
||
### 輸入框
|
||
#### 當輸入框有參數時，觸發"測試按鈕"會呼叫text_click這個function，將輸出框的參數改得與輸入框相同
|
||
```
|
||
<!--HTML-->
|
||
<input id="text_in_id"/>
|
||
<button onclick="text_click()">測試按鈕</button>
|
||
<input id="text_out_id"/>
|
||
<!--JS-->
|
||
<script>
|
||
function text_click() {
|
||
var in_text = document.getElementById("text_in_id").value
|
||
console.log(in_text)
|
||
document.getElementById('text_out_id').value = in_text
|
||
}
|
||
</script>
|
||
```
|
||
其中包含使用DOM，這邊可以好好熟悉這塊，雖然無論是呼叫Name或是Id都可以獲得正確參數，但這邊建議使用Id，有時候寫入框架的時候，會遇到框架本身會需要呼叫某元件，因此將Name給框架使用
|
||
|
||
### 警告視窗
|
||
#### 彈出視窗，可以用於debug，或是有物品輸入不正確，跳出警示
|
||
```
|
||
<button onclick="alert('這是警告文字');">開啟警告視窗</button>
|
||
```
|
||
|
||
|
||
### 表格
|
||
#### 基礎布局時最常用到的
|
||
```HTML
|
||
<table>
|
||
<tr>
|
||
<th>First name</th>
|
||
<th>Last name</th>
|
||
</tr>
|
||
<tr>
|
||
<td>John</td>
|
||
<td>Doe</td>
|
||
</tr>
|
||
<tr>
|
||
<td>Jane</td>
|
||
<td>Doe</td>
|
||
</tr>
|
||
</table>
|
||
```
|
||
|
||
|
||
##
|
||
## 與後端撈值
|
||
### 由於需要大量參數，通常都會跟webapi去索取資料，這邊使用最常用的方式Jquery的AJAX
|
||
若無jq包，先載入後才能使用以下操作
|
||
``` javascript
|
||
<script src='//ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js'></script>
|
||
```
|
||
|
||
### 獲取資料
|
||
```javascript
|
||
function get_data(){
|
||
$.ajax({
|
||
type: "GET", //選擇格式(GET，POST，PUT，DELETE)
|
||
url: "/api/get_data", //換取網址
|
||
data: {},
|
||
contentType: "application/json",//指定格式(就抱持這樣即可)
|
||
success: function (Model) {
|
||
console.log(Model)
|
||
}
|
||
});
|
||
}
|
||
```
|
||
### 新增資料
|
||
```javascript
|
||
function post_data(){
|
||
var obj = { parking_spaces_name: '第一停車場', parking_spaces_total_num: "20", longitude: "23.156", latitude: "120.123" }
|
||
var stringify_obj = JSON.stringify(obj);
|
||
$.ajax({
|
||
type: "POST",
|
||
url: "http:/x.x.x.x:7777/api/test", //API網址
|
||
data: stringify_obj, //資料包
|
||
contentType: "application/json",
|
||
success: function (msg) {
|
||
console.log(msg)
|
||
}
|
||
});
|
||
}
|
||
```
|
||
### 刪除資料
|
||
```javascript
|
||
function delet_data(){
|
||
$.ajax({
|
||
type: "DELETE",
|
||
url: "http:/x.x.x.x:7777/api/test", //API網址,
|
||
data: {},
|
||
contentType: "application/json",
|
||
success: function (msg) {
|
||
console.log(msg)
|
||
}
|
||
});
|
||
}
|
||
```
|
||
### 更新資料
|
||
```javascript
|
||
function put_data(){
|
||
$.ajax({
|
||
type: "PUT",
|
||
url: "http:/x.x.x.x:7777/api/test", //API網址,
|
||
data: stringify_obj,
|
||
contentType: "application/json",
|
||
success: function (Model) {
|
||
console.log(Model)
|
||
}
|
||
});
|
||
}
|
||
```
|
||
##
|
||
## 會以上這些後，即可開始製作屬於自己的網站
|
||
### 最常用的都是以上這些，剩下的就靠練習累積上去了，網站建立其實沒想像的困難
