我有两个PHP变量.我想创建一个read more按钮来切换这两个值,一个是摘录,另一个是完整内容.我是PHP和jQuery的新手.花了几个小时试图解决这个问题:(如果有人可以提供帮助,我真的很感激…
我试图改变id和class来实现我的目标.我相信这可能真的很愚蠢.但我真的不知道聪明的方式.
请问有人给我一些方向吗？现在,我在代码中输入的警报返回“未完成”…
PHP：
$trimmed = '<p id="short_desc" class="show_desc">' . chinese_excerpt( get_the_content(),$lenth = 260 ) . '</p>';
$full = '<p id="full_desc" class="hide_desc">' . get_the_content() . '</p>';
echo apply_filters( 'the_resume_description',$trimmed );
echo apply_filters( 'the_resume_description',$full );
echo '<div style="float:right; margin-top:-30px"><div id="show_more">Read More...</div></div>'
HTML：
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$( document ).ready( function () {
$( "#show_more" ).click( function ( ) {
if ( $( '#short_desc' ).attr( 'id' ) === "short_desc" ) {
$( "#short_desc" ).removeClass("show_desc");
$( "#short_desc" ).addClass("hide_desc");
$( "#short_desc" ).attr( 'id',$( "#full_desc" ) );
$( "#full_desc" ).removeClass("hide_desc");
$( "#full_desc" ).addClass("show_desc");
} else if ( $( '#full_desc' ).attr( 'id' ) === "full_desc" ){
$( "#full_desc" ).removeClass("show_desc");
$( "#full_desc" ).addClass("hide_desc");
$( "#full_desc" ).attr( 'id',"#short_desc" );
alert($( '#short_desc' ).attr( 'id' ));
$( "#short_desc" ).removeClass("hide_desc");
$( "#short_desc" ).addClass("show_desc");
};
} );
} );
</script>
非常感谢你！
