问题描述
我已经创建了一个JQuery列表,我希望从数据库中填写车牌号码,为此,我创建了一个新的cfm文件并让它在html中输出我想要的内容,以便稍后我可以将其转换像这样:
I have made a JQuery list that I want to fill up with license plate numbers from a database, and to do so, I created a new cfm file and had it output what I wanted in html so I could just convert it later like this:
setPlates.cfm
setPlates.cfm
<cfquery name="q_sample" datasource="cars_live">
SELECT LICENSE FROM veh_rec
</cfquery>
<cfoutput query="q_sample" >
<li><a href='#Student'>#license#</a></li>
</cfoutput>
我调用get函数进入setPlates.cfm文件,这样我就可以添加许可证了数据库作为我列表中的项目。代码如下:
I call the get function to go into the setPlates.cfm file so I can add the license plates from the database as items in my list. Code is below:
<div class="ui-grid-solo">
<div class="ui-block-a"><br></div>
<div class="ui-block-a"><ul id="plates" data-role="listview" data-inset="true" data-filter="true" data-filter-reveal="true" data-filter-placeholder="Filter Students">
<script type="text/javascript">
$.get("setPlates.cfm")
.done(function(data) {
$("#plates").html(data);
});
</script>
<div id="plates"></div>
</ul></div>
</div><!-- /grid solo -->
事情是,当它转到那个新文件并开始读取输出时,#Student会混淆它,因为它试图将其作为数据库中的变量读取。 #Student是一个将页面更改为新页面的调用,该页面将根据选择的牌照列出学生信息(例如他们是否拥有停车许可证)。有没有办法让它将英镑符号视为文本,而不是像#certault#?有点像你会在java中使用字符串中的引号吗?
Thing is, when it goes to that new file and starts reading the output, the #Student confuses it, because it's trying to read it as a variable in the database. #Student is a call to change pages to a new page which will list student information (like whether or not they own a parking permit) based on which license plate was selected. Is there a way to make it treat that pound sign as text, as opposed to the start of something like #license#? Kind of like you would do \" to use quotes inside of a string in java?
另外,如果我从学生面前删除#,所有许可证盘子出现在列表中,但他们没有带我到我想要到达的学生页面。
Also, if I remove the # from in front of student, all the license plates show up in the list, but they dont take me to the student page I'm trying to reach.
推荐答案
当你知道,#
在coldfusion中是一个特殊字符,用于包装变量,以便在cfoutput内部或其他特定内容时输出变量的内容标签,例如cfmail。如果你想在你的文本中使用#
,你必须通过放置第二个#
就在旁边。
As you know, #
in coldfusion is a special character that is used to wrap a variable so that it outputs the contents of the variable when you are inside of a cfoutput or inside of other specific tags, such as cfmail. If you want to use #
in your text, you must escape it by placing a second #
right next to it.
<cfoutput>
the item## is #itemnumber#
</cfoutput>
当你进入coldfusion标签的属性时,更进一步,您可以使用在coldfusion标记的属性中的字符串中转义
。
Taking this a step further, when you're inside of a coldfusion tag's attribute, you can use ""
to escape "
within a string in an attribute of a coldfusion tag.
我在你的情况下,我会这样做:
In your case, i'd do this:
<cfoutput query="q_sample" >
<li><a href='##Student'>#q_sample.license#</a></li>
</cfoutput>
或者这个:
<cfloop query="q_sample" >
<li><a href='#Student'><cfoutput>#q_sample.license#</cfoutput></a></li>
</cfloop>
注意,我在变量中添加了 q_sample
名字,因为这是一个很好的做法。
Note, i added q_sample
to the variable name because it's a good practice.
