# 去掉 WordPress 脚本中的版本号

WordPress为了能给用户提供最新的脚本以及样式表的版本，使用回调函数生成相关HTML。但是这样生成的HTML不能实现缓存,而且不利于SEO结构化,那么我们来去掉这些讨厌的静态资源中的版本号吧.



你常常能看到这个吧

```
<script type="text/javascript" src="http://你的网站/wp-includes/js/jquery/jquery.js?=1.71"></script>
```

如果你也觉得这个版本号碍事，而又不想影响wordpress其他功能的话，只需要小小修改一下，就能解决问题了。
打开wp-includes/class.wp-scripts.php文件,找到此处

```php
if ( isset($this->args[$handle]) )
	$ver = $ver ? $ver . '&amp;' . $this->args[$handle] : $this->args[$handle];
	$src = $this->registered[$handle]->src;
```

你可以在那行代码下添加一个新的赋值语句，也可以把上面2行判断直接删除。

```php
if ( isset($this->args[$handle]) )
	$ver = $ver ? $ver . '&amp;' . $this->args[$handle] : $this->args[$handle];
$ver ='';
	$src = $this->registered[$handle]->src;
```

至此，wordpress生成的脚本，样式代码中就不会出现版本号了。

如果你愿意的话,可以用我修改过的函数替换掉你原来的函数

```php
	function do_item( $handle, $group = false ) {
		if ( !parent::do_item($handle) )
			return false;

		if ( 0 === $group && $this->groups[$handle] > 0 ) {
			$this->in_footer[] = $handle;
			return false;
		}

		if ( false === $group && in_array($handle, $this->in_footer, true) )
			$this->in_footer = array_diff( $this->in_footer, (array) $handle );

		$src = $this->registered[$handle]->src;

		if ( $this->do_concat ) {
			$srce = apply_filters( 'script_loader_src', $src, $handle );
			if ( $this->in_default_dir($srce) ) {
				$this->print_code .= $this->print_extra_script( $handle, false );
				$this->concat .= "$handle,";
				$this->concat_version .= "$handle";
				return true;
			} else {
				$this->ext_handles .= "$handle,";
				$this->ext_version .= "$handle";
			}
		}

		$this->print_extra_script( $handle );
		if ( !preg_match('|^https?://|', $src) && ! ( $this->content_url && 0 === strpos($src, $this->content_url) ) ) {
			$src = $this->base_url . $src;
		}


		$src = esc_url( apply_filters( 'script_loader_src', $src, $handle ) );

		if ( $this->do_concat )
			$this->print_html .= "<script type='text/javascript' src='$src'></script>\n";
		else
			echo "<script type='text/javascript' src='$src'></script>\n";

		return true;
	}
```

样式表后面的版本号比如style.css?3.3也可以这么去掉,修改class.wp-styles.php即可

/**
 * BackPress Styles enqueue.
 *
 * These classes were refactored from the WordPress WP_Scripts and WordPress
 * script enqueue API.

		echo "</style>\n";

	}

	function all_deps( $handles, $recursion = false, $group = false ) {
		$r = parent::all_deps( $handles, $recursion );
		if ( !$recursion )
			$this->to_do = apply_filters( 'print_styles_array', $this->to_do );
		return $r;
	}

	function _css_href( $src, $handle ) {
		if ( !is_bool($src) && !preg_match('|^https?://|', $src) && ! ( $this->content_url && 0 === strpos($src, $this->content_url) ) ) {
			$src = $this->base_url . $src;
		}

		$src = apply_filters( 'style_loader_src', $src, $handle );
