6个容易被忽略的smarty 标签使用
6个容易被忽略的smarty 标签使用
原文转载地址:http://www.jb100.net/html/content-22-872-1.html
1,capture标签
capture的中文意思是抓取,它的作用是抓取模板输出的数据,当我们需要它的时候,调用它,以得到抓取数据的目的。例子:
{capture name=test}
{/capture}
{$smarty.capture.test}
说明:
在{capture name="test"}和{/capture}之间的内容被存储到变量$test中,该变量由name属性指定.在模板中通过 $smarty.capture.test 访问该变量.如果没有指定name 属性,函数默认将使用"default" 作为参数,这一点很jquery中的clone
2,config_load标签
config_load可以直接将文件中的内容读取出来,这样可以省掉assign这一步。
test.csv:
pageTitle = "config_load_test"
bodyBgColor = "#eeeeee"
img = "girl.jpg"
width="100"
height="100"
index.tpl:
{config_load file="test.csv"}

上述过程中如果出现这样的问题Warning: Smarty error: unable to read resource, 请查看一下,你的test.csv是不是放在smarty的配置目录中,默认配置目录是configs
/**
* The directory where config files are located.
*
* @var string
*/
var $config_dir = 'configs';
3,literal标签的使用
做web开发,难免会写一些JS,jquery代码。js和jquery里面都会{}这样的符号,smarty会不会把它理解成php的变量呢?如果你不加literal标签的话,smarty肯定会把它理解变量了,加了就不会,例如:
{literal}
function getAbsLeft(e){
var l=e.offsetLeft;
while(e=e.offsetParent)l+=e.offsetLeft;
return l;
}
function getAbsTop(e){
var t=e.offsetTop;
while(e=e.offsetParent)t+=e.offsetTop;
return t;
}
{/literal}
4,php标签
当你习惯了assign后,你有没有想过,在模板文件里面直接写php代码呢,我想有的时候你肯定很想吧。例如:
{php}
global $result;
foreach($result as $key=>$value){
echo "key=$key,value=>$value
";
}
{/php}
5,strip标签
strip标签去除标签内的空格和回车,这一点我觉得,做手机开发的朋友肯定用的到,因为全角空格有可能会导致整个页面错乱,甚至是一个空白页面。手机屏幕小,估计用smarty的可能性也比较小。
{strip}
strip
{/strip}
6,fetch标签
fetch标签根php的file_get_contents挺想的,都可以把文件中的内容读出来,并且是个字符串的形势
{fetch file="./aaaa.txt" assign="result"}
{if is_array($result)}
is array
{else if}
not array
{/if}

Java Selection Sorting Method Code Writing Guide and Examples Selection sorting is a simple and intuitive sorting algorithm. The idea is to select the smallest (or largest) element from the unsorted elements each time and exchange it until all elements are sorted. This article will provide a code writing guide for selection sorting, and attach specific Java sample code. Algorithm Principle The basic principle of selection sort is to divide the array to be sorted into two parts, sorted and unsorted. Each time, the smallest (or largest) element is selected from the unsorted part and placed at the end of the sorted part. Repeat the above
