        if(inner_text=='Send Request'){

        var post_id=<?php echo $blog_id  ;?>;

        var event_date='<?php echo $blog_feeds['valid_date'] ?>';
        var post_text='<?php echo addslashes($blog_feeds['post_text'])  ?>'; //if the string contains ' , then would have error
        var request_text_id='<?php echo $blog_id.'comment_text';?>';


        var request_content=$('#'+request_text_id).val();
        var who_post='<?php echo $blog_feeds['username']  ;?>';


        $.ajax({
        url:'php/join_request.php',
        method:'post',
        data:{request_content:request_content,post_id:post_id,who_post:who_post,event_date:event_date,post_text:post_text},
        success:function(data){

        if(data=='ok'){


            $('<?php echo '#'.$blog_id.'request_w' ?>').html('You have sent '+who_post+' a joining reuqest on this event');
            $('<?php echo '#'.$blog_id.'request_button'; ?>').html('Request Sent');
            $('<?php echo '#'.$blog_id.'request_button'; ?>').css('opacity','0.7');
            $('<?php echo '#'.$blog_id.'request_button'; ?>').css('cursor','initial');
            $('<?php echo '#'.$blog_id.'comment_text';?>').val('');
        }


        }
        })
        }
        "    id="<?php echo $blog_id.'request_button'; ?>" class="j_request_button">



        <?php
        $select_request=mysql_query("SELECT `id` FROM `join_request` WHERE `post_id`='$blog_id' AND `who_request`='$username'");


        if(mysql_num_rows($select_request)>=1){
        echo '<span style="opacity:0.7;cursor:initial">Request Sent</span>';

    }
        else{

        echo '<span style="cursor:pointer">Send Request</span>';

        }
        ?>
        </span>

如果我在if语句之前添加一个alert(inner_text),我可以成功提醒“已发送请求”,但我无法在if语句中提示ok

尝试:

var inner_text=$.trim($(this).text());

这将删除任何周围的空格,如果您的跨度之间有换行符,则很可能。

不要在HTML中放置这样的完整脚本。给你的span一个id,并在一个单独的脚本标记中使用jQuery:

<span id="sent_request">sent request</span>
<script>
  $('#sent_request').click(function(){
    var inner_text=$(this).text();
    if(inner_text=='sent request'){
      alert('ok'); //not working
    }
  });
</script>
