我有这个脚本：

＆＃13;

<input type="number" id="userInput"=></input>
<button onclick="test()">Submit</button>
<p id="cmdpvp"></p>
<p id="cmdsafe"></p>
<p id="cmdscore"></p>
<script type="text/javascript">

function test(){
    var userInput = document.getElementById("userInput").value;
    var x = 20;
    var y = parseInt(userInput)
	var z = x + y;
    document.getElementById("cmdpvp").innerHTML = '<p><b>Command for PVPZone:</b></p><br><textarea rows="10" cols="100" id="html" name="html">/summon falling_block ~ ~1 ~ <br> {Block:command_block,Time:1,TileEntityData:<br>{Command:"/fill ~-1 ~-3 ~-2 ~3 ~-8 ~1 bedrock 0 hollow"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~0 ~-8 ~-1 minecraft:command_block 0 replace {Command:\"effect @a[r=' + z + ',score_PVPZone=1] minecraft:mining_fatigue 0 0\"}"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~0 ~-8 ~-1 minecraft:command_block 0 replace {Command:\"effect @a[r=' + z + ',score_PVPZone=1] minecraft:regeneration 0 0\"}"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~1 ~-11 ~0 minecraft:command_block 0 replace {Command:\"gamemode 0 @a[r=' + z + ',score_PVPZone=0]\"}"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~1 ~-11 ~0 command_block 0 replace {Command:\"scoreboard players set @a[r=' + z + ',score_PVPZone=0] PVPZone 1\"}"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~1 ~-11 ~0 command_block 0 replace {Command:\"scoreboard players set @a[r=' + z + ',score_SafeZone_min=1] SafeZone 0\"}"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~0 ~-11 ~0 repeating_command_block 0 replace {auto:1b,Command:\"testfor @a[r=' + userInput + ',score_PVPZone=0]\"}"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~1 ~-12 ~0 minecraft:unpowered_comparator 1"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~2 ~-13 ~0 command_block 0 replace {Command:\"fill ~-1 ~-1 ~-1 ~-1 ~-3 ~-1 minecraft:redstone_block\"}"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~2 ~-17 ~-1 command_block 0 replace {Command:\"tellraw @a[r=' + z + ',score_PVPZone=0] [\\\"\\\",{\\\"text\\\":\\\"WARNING!!!!\\\",\\\"color\\\":\\\"red\\\"},{\\\"text\\\":\\\" You are now in the PVPZone!\\\"}]\"}"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~2 ~-17 ~-1 command_block 0 replace {Command:\"fill ~-1 ~-1 ~ ~-1 ~1 ~ minecraft:air\"}"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~2 ~-19 ~0 glowstone"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/setblock ~0 ~-20 ~0 glowstone"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/fill ~ ~-14 ~-1 ~ ~2 ~ air"},Passengers:<br>[{id:falling_block,Block:command_block,Time:1,TileEntityData:<br>{Command:"/fill ~ ~-15 ~-1 ~ ~ ~-1 redstone_block"},Passengers:<br>[{id:falling_block,Block:redstone_block,Time:1<br>}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}]}</textarea><input type="button" value="Copy PVPZone" onclick="copy_to_clipboard(html);">';

javascript是一个html网页。输入一个数字，然后生成一个脚本。我知道它可能不是很聪明，而且方法更简单。当您单击提交按钮并出现一个脚本时，它会显示＆lt; br＆gt;作为文字。当它的内部HTML时，它不能工作吗？谁能解释一下？

Answer 1

一种方法是使用正则表达式来查找和替换所有br

以下是用新行替换它的那个：

.replace(/<br\s*\/?>/g, '\n')

如果您想创建自己的正则表达式并将其与“.replace”一起使用，Rubular是一个很好的资源！

为什么javascript显示<br/> as astext
