使用 jQuery/PHP 删除通配符

发布于 2024-11-08 15:37:18 字数 557 浏览 1 评论 0原文

嘿伙计们,我希望我能够尽可能简单地解释这一点。基本上我正在编译一个列表,为此我需要删除某个触发词后的大量文本。

我想要实现的示例在这里

假设我刚刚在文本中粘贴了一堆文本框,我希望除了第一个用户名之外的所有内容都被删除。

例子是...

流氓从 youaref0rsaken 转发了此

内容 youaref0rsaken 从 loveeoutoflust 转发了

此内容 loveeoutoflust 从 yourwatchfuleye 转发了此

内容 我想将其变成

流氓

youaref0rsaken

loveeoutoflust

使用带有输入的文本框、一个按钮和一个显示输出的文本框。我尝试使用 jquery 和 php preg_replace 执行此操作,但无法使其正常运行。

有人能帮我解决这个问题吗?

Hey guys, I hope I am able to explain this as easy as possible. Basically I am compiling a list and to do so I need to remove a load of text after a certain trigger word.

Example of what I am trying to achieve is here

Say I have just pasted a bunch of text in my text box, I want everything removed apart from the first username.

And example would be...

r-u-f-f-i-a-n reblogged this from youaref0rsaken

youaref0rsaken reblogged this from loveeoutoflust

loveeoutoflust reblogged this from yourwatchfuleye

Which I would want to turn in to

r-u-f-f-i-a-n

youaref0rsaken

loveeoutoflust

With using a textbox with the input, a button and a textbox which would display the output. I have tried doing this using jquery and php preg_replace but cannot get it to function correctly.

Is anyone able to help me with this?

$pattern = '/reblogged this from [\w]+/';
$string = "r-u-f-f-i-a-n reblogged this from youaref0rsaken youaref0rsaken reblogged this from loveeoutoflust loveeoutoflust reblogged this from yourwatchfuleye";
echo preg_replace( $pattern, '', $string);

会给你结果

r-u-f-f-i-a-n youaref0rsaken loveeoutoflust 
$pattern = '/reblogged this from [\w]+/';
$string = "r-u-f-f-i-a-n reblogged this from youaref0rsaken youaref0rsaken reblogged this from loveeoutoflust loveeoutoflust reblogged this from yourwatchfuleye";
echo preg_replace( $pattern, '', $string);

will give you as result

r-u-f-f-i-a-n youaref0rsaken loveeoutoflust

<罢工>
以 javascripts Replace funciton

string.replace(regexp/substr,newstring)

为例,使用下面的代码查看此小提琴 http://jsfiddle.net/ vwhCx/
注意:如果正则表达式的概念对您来说是新的,那么这里唯一需要知道的是:/reblogged from/g 是//g 表示全球范围内,或多个匹配。

<div id="boxy-1"> r-u-f-f-i-a-n reblogged this from youaref0rsaken youaref0rsaken reblogged this from loveeoutoflust loveeoutoflust reblogged this from yourwatchfuleye </div>

<button>transform</button>
<script type="Text/javascript">
$(document).ready(function() {
  $('button').click(function() {
    //get text from box
    var str = $('#boxy-1').text()
    //empty box
    $('#boxy-1').empty();
    //insert formatted sting 
    $('#boxy-1').append(str.replace(/reblogged this from/g, ' '));
  });
)};

</script>

更新

根据您的评论

我已经更改了我的代码以在文本区域上工作使用这个

<textarea id="boxy-1"> r-u-f-f-i-a-n reblogged this from youaref0rsaken youaref0rsaken reblogged this from loveeoutoflust loveeoutoflust reblogged this from yourwatchfuleye</textarea>

<button>transform</button>

<script type="text/javascript">
$(document).ready(function() {
  $('button').click(function() {
    //get text from box
    var str = $('#boxy-1').text()
    //empty box
    $('#boxy-1').empty();
    //insert formatted sting 
    $('#boxy-1').val(str.replace(/reblogged this from/g, ' '));
 });
});

新的实时示例:http://jsfiddle.net/K3LZU/

LAST EDIT

如果您尝试将其显示为列表或换行符,请尝试 str.replace(/reblogged this from/g, ' \n') \n 表示换行符


look into javascripts replace funciton

string.replace(regexp/substr,newstring)

as an example check out this fiddle using the code below http://jsfiddle.net/vwhCx/
note: if the concept of a regexp is new to you the only thing to know here: /reblogged this from/g is that the //g means globeably, or more than one match.

<div id="boxy-1"> r-u-f-f-i-a-n reblogged this from youaref0rsaken youaref0rsaken reblogged this from loveeoutoflust loveeoutoflust reblogged this from yourwatchfuleye </div>

<button>transform</button>
<script type="Text/javascript">
$(document).ready(function() {
  $('button').click(function() {
    //get text from box
    var str = $('#boxy-1').text()
    //empty box
    $('#boxy-1').empty();
    //insert formatted sting 
    $('#boxy-1').append(str.replace(/reblogged this from/g, ' '));
  });
)};

</script>

UPDATE

based on your comment I have altered my code to work on a text area

use this

<textarea id="boxy-1"> r-u-f-f-i-a-n reblogged this from youaref0rsaken youaref0rsaken reblogged this from loveeoutoflust loveeoutoflust reblogged this from yourwatchfuleye</textarea>

<button>transform</button>

<script type="text/javascript">
$(document).ready(function() {
  $('button').click(function() {
    //get text from box
    var str = $('#boxy-1').text()
    //empty box
    $('#boxy-1').empty();
    //insert formatted sting 
    $('#boxy-1').val(str.replace(/reblogged this from/g, ' '));
 });
});

LAST EDIT

if you are trying to display it as a list, or newlines try str.replace(/reblogged this from/g, '\n') the \n indicating a newline

如果它始终是第一个单词,您可以执行以下简单操作:

$s = 'youaref0rsaken reblogged this from loveeoutoflust';
$a = explode(' ',$s);
echo $a[0];

If it's always the first word, you can do something simple like this:

$s = 'youaref0rsaken reblogged this from loveeoutoflust';
$a = explode(' ',$s);
echo $a[0];
