Embed javascript in PHP echo
提问by benhowdle89
echo "<td> + manuf + </td>";
Is this above ever going to work??
上面的这个能用吗？？
I'm pulling results from a mysql db to edit the contents but need the jQuery functionality to edit it, hence the embedded javascript variable...
我正在从 mysql db 中提取结果来编辑内容，但需要 jQuery 功能来编辑它，因此嵌入了 javascript 变量...
EDIT:
编辑：
Sorry for the lack of context, its related to another question i've asked on here Mysql edit users orders they have placedthis is the end goal. To edit the order i place, i need to pull the results into an environment similar to how the user placed the order. So my thinking was to include the jQuery functionality to add items to a cart etc, then they could press submit and in the same way i used .Ajax to post the data to an insert php script i would post the values to an update php script! Is this backwards thinking, any advice welcomed!
抱歉缺乏上下文，它与我在此处提出的另一个问题有关，Mysql 编辑用户下的订单是最终目标。要编辑我下的订单，我需要将结果提取到类似于用户下订单的环境中。所以我的想法是包含 jQuery 功能以将项目添加到购物车等，然后他们可以按提交，并以我使用 .Ajax 将数据发布到插入 php 脚本的相同方式我会将值发布到更新 php 脚本！这是逆向思维吗，欢迎任何建议！

I suggest you take a look at the follwing.
我建议你看看下面的。
Now your simplest solution under you circumstances is to do go for the json_encodemethod. Let me show you an example:
现在，在您的情况下，您最简单的解决方案是使用json_encode方法。让我给你看一个例子：
$json_data = array(
'manuf' => $some_munaf_data
);
echo "<script type=\"text/javascript\">";
echo "var Data = " . json_encode(json_data);
echo "</script>";
This will produce an object called Data, and would look like so:
这将产生一个名为 的对象Data，看起来像这样：
<script type="text/javascript">
var Data = {
munaf : "You value of $some_munaf_data"
}
</script>
Then when you need the data just use Data.munafand it will hold the value from the PHP Side.
然后，当您需要数据时，只需使用Data.munaf它，它就会保存来自 PHP 端的值。

Would you not echo out the jQuery within a Javascript code island? You need the client-based code (jQuery) to be able to execute after the server-side code (PHP).
您不会在 Javascript 代码岛中回显 jQuery 吗？您需要基于客户端的代码 (jQuery) 才能在服务器端代码 (PHP) 之后执行。
echo '<td><script language = "JavaScript" type = "text/JavaScript">document.write("");</script></td>';

Try just emitting the MySQL content with PHP:
尝试只用 PHP 发出 MySQL 内容：
echo "<td id='manuf'>".$manuf."</td>"
Then get the contents with jQuery like this:
然后像这样使用 jQuery 获取内容：
var manuf = $('#manuf').text();

Consume you have the table echoed with php:
消费你有与 php 相呼应的表：
<table id="sometab">
<tr>
<td>
</td>
<tr>
</table>
The jquery for printing resuls in any td is :nth-child(2) takes 2 table td object :
在任何 td 中打印结果的 jquery 是 :nth-child(2) 需要 2 个表 td 对象：
<script type="text/javascript">
$(function(){
$("#sometab tr td:nth-child(2)").html("bla");
})
</script>

i think you cant embed the jquery variable in the php like this . you just give the class name here from here when edit will be click you will get the variable as in submit click in other questions .
我认为你不能像这样在 php 中嵌入 jquery 变量。您只需在此处提供类名，当点击编辑时，您将获得变量，如在其他问题中提交点击一样。

Is "manuf" a JS variable or part of a PHP output e.g. part of generated ?
“manuf”是 JS 变量还是 PHP 输出的一部分，例如生成的一部分？
Basically this can easily be done by: mysql thru PHP(*I can't put table tag..sorry.):
基本上这可以通过以下方式轻松完成：mysql thru PHP（*我不能放置表标签..抱歉。）：
while($row = mysql_fetch_object($result)) {
echo 'tr';
echo 'td a href="#" class="myres"'.$row->manuf.'/a /td';
echo '/tr';
}
then on your JS just attach a "click" handler
然后在你的 JS 上附加一个“点击”处理程序
$(function() {
$(".myres").click(function() {
//my update handler...
});
});

Nope. You'd need to output valid JavaScript for the browser to interpret:
不。您需要输出有效的 JavaScript 以供浏览器解释：
echo "<script>document.write('<td>'+manuf+'</td>')</script>";
But that is a dreadful construct, and I can't really see why you would need this, seeing as the td's contents are likely to be static at first.
但这是一个可怕的结构，我真的不明白你为什么需要这个，因为td的内容一开始可能是静态的。
