javascript - 为什么 String.replace 会缩短我的字符串？

Question

我制作了一个脚本来动态更改字符串以满足我的需要。它应该可以替换字符串内的标记(“[pid]”，“[dir]”，“[+X]”)。但是，我发现 string.replace() 方法存在问题，该方法会剪切字符串，留下重要信息。

最终字符串应如下所示(放入代码示例中以提高可读性):

'summon FallingSand ~ ~4 ~ {Time:1,Data:0,TileID:152,Riding:{id:FallingSand,DropItem:0b,Time:1,Block:minecraft:command_block,TileEntityData:{Command:fill ~ ~1 ~-1 ~ ~-5 ~ air},Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:1,Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:152,Riding:{id:FallingSand,DropItem:0b,Time:1,Block:minecraft:command_block,TileEntityData:{Command:kill @e[type=MinecartCommandBlock,r=4]},Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:1,Riding:{id:MinecartCommandBlock,Command:setblock ~ ~ ~ air,Riding:{id:MinecartCommandBlock,Command:/kill @e[type=Item,r=4],Riding:{id:MinecartCommandBlock,Command:/tellraw @a {text:"Thanks to gentlegiantJGC and xafonyz for making the MCedit filter to make this possible",color:gold},Riding:{id:MinecartCommandBlock,Command:"setblock ~2 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,Command:"setblock ~3 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,Command:"setblock ~4 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,Command:buffer,Riding:{id:MinecartCommandBlock,Command:buffer,Riding:{id:MinecartCommandBlock,Command:"setblock ~2 ~-2 ~-4 minecraft:command_block 1 replace {CustomName:\"@\",Command:\"/execute @a ~ ~ ~ /execute @e[type=ArmorStand,name=ParticleEmitterDisplay,score_pe_particle_min=3,score_pe_particle=3,score_pe_dir_min=8,score_pe_dir=8,score_pe_ctrl5_min=1,score_pe_ctr5=1,r=32] 0 -2 0 particle smoke ~ ~ ~ 0 -10 0 0.1 0 force\",x:41,y:1,z:-79,id:\"Control\"}",Riding:{id:MinecartCommandBlock,Command:"setblock ~2 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,Command:"setblock ~2 ~-2 ~-2 minecraft:command_block 1 replace {CustomName:\"@\",Command:\"/execute @a ~ ~ ~ /execute @e[type=ArmorStand,name=ParticleEmitterDisplay,score_pe_particle_min=3,score_pe_particle=3,score_pe_dir_min=9,score_pe_dir=9,score_pe_ctrl5_min=1,score_pe_ctr5=1,r=32] 0 3 0 particle smoke ~ ~ ~ 0 10 0 0.1 0 force\",x:41,y:1,z:-77,id:\"Control\"}",Riding:{id:MinecartCommandBlock,Command:"setblock ~3 ~-2 ~-4 minecraft:command_block 1 replace {CustomName:\"@\",Command:\"/execute @a ~ ~ ~ /execute @e[type=ArmorStand,name=ParticleEmitterDisplay,score_pe_particle_min=3,score_pe_particle=3,score_pe_dir_min=10,score_pe_dir=10,score_pe_ctrl5_min=1,score_pe_ctr5=1,r=32] 0 0.5 -2 particle smoke ~ ~ ~ 0 0 -10 0.1 0 force\",x:42,y:1,z:-79,id:\"Control\"}",Riding:{id:MinecartCommandBlock,Command:"setblock ~3 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,Command:"setblock ~3 ~-2 ~-2 minecraft:command_block 1 replace {CustomName:\"@\",Command:\"/execute @a ~ ~ ~ /execute @e[type=ArmorStand,name=ParticleEmitterDisplay,score_pe_particle_min=3,score_pe_particle=3,score_pe_dir_min=11,score_pe_dir=11,score_pe_ctrl5_min=1,score_pe_ctr5=1,r=32] 0 0.5 2 particle smoke ~ ~ ~ 0 0 10 0.1 0 force\",x:42,y:1,z:-77,id:\"Control\"}",Riding:{id:MinecartCommandBlock,Command:"setblock ~4 ~-2 ~-4 minecraft:command_block 1 replace {CustomName:\"@\",Command:\"/execute @a ~ ~ ~ /execute @e[type=ArmorStand,name=ParticleEmitterDisplay,score_pe_particle_min=3,score_pe_particle=3,score_pe_dir_min=13,score_pe_dir=13,score_pe_ctrl5_min=1,score_pe_ctr5=1,r=32] 2 0.5 0 particle smoke ~ ~ ~ 10 0 0 0.1 0 force\",x:43,y:1,z:-79,id:\"Control\"}",Riding:{id:MinecartCommandBlock,Command:"setblock ~4 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,Command:"setblock ~4 ~-2 ~-2 minecraft:command_block 1 replace {CustomName:\"@\",Command:\"/execute @a ~ ~ ~ /execute @e[type=ArmorStand,name=ParticleEmitterDisplay,score_pe_particle_min=3,score_pe_particle=3,score_pe_dir_min=12,score_pe_dir=12,score_pe_ctrl5_min=1,score_pe_ctr5=1,r=32] -2 0.5 0 particle smoke ~ ~ ~ -10 0 0 0.1 0 force\",x:43,y:1,z:-77,id:\"Control\"}",Riding:{id:MinecartCommandBlock,Command:buffer,Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:157,Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:152,Riding:{id:Item,Age:5996,Motion:[0.0,0.0,-0.1]}}}}}}}}}}}}}}}}}}}}}}}}}}}'

但是，它是这样的:

'summon FallingSand ~ ~4 ~ {Time:1,Data:0,TileID:152,Riding:{id:FallingSand,DropItem:0b,Time:1,Block:minecraft:command_block,TileEntityData:{Command:fill ~ ~1 ~-1 ~ ~-5 ~ air},Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:1,Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:152,Riding:{id:FallingSand,DropItem:0b,Time:1,Block:minecraft:command_block,TileEntityData:{Command:kill @e[type=MinecartCommandBlock,r=4]},Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:1,Riding:{id:MinecartCommandBlock,Command:setblock ~ ~ ~ air,Riding:{id:MinecartCommandBlock,Command:/kill @e[type=Item,r=4],Riding:{id:MinecartCommandBlock,Command:/tellraw @a {text:"Thanks to gentlegiantJGC and xafonyz for making the MCedit filter to make this possible",color:gold},Riding:{id:MinecartCommandBlock,Command:"setblock ~2 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,Command:"setblock ~3 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,<b>Com...</b> ~ ~ /execute @e[type=ArmorStand,name=ParticleEmitterDisplay,score_pe_particle_min=3,score_pe_particle=3,score_pe_dir_min=12,score_pe_dir=12,score_pe_ctrl5_min=1,score_pe_ctr5=1,r=32] -2 0.5 0 particle smoke ~ ~ ~ -10 0 0 0.1 0 force",x:43,y:1,z:-79,id:"Control"}",Riding:{id:MinecartCommandBlock,Command:"setblock ~4 ~-2 ~-3 minecraft:redstone_block 0 destroy",Riding:{id:MinecartCommandBlock,Command:"setblock ~4 ~-2 ~-2 minecraft:command_block 1 replace {CustomName:"@",Command:"/execute @a ~ ~ ~ /execute @e[type=ArmorStand,name=ParticleEmitterDisplay,score_pe_particle_min=3,score_pe_particle=3,score_pe_dir_min=13,score_pe_dir=13,score_pe_ctrl5_min=1,score_pe_ctr5=1,r=32] 2 0.5 0 particle smoke ~ ~ ~ 10 0 0 0.1 0 force",x:43,y:1,z:-77,id:"Control"}",Riding:{id:MinecartCommandBlock,Command:buffer,Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:157,Riding:{id:FallingSand,DropItem:0b,Time:1,Data:0,TileID:152,Riding:{id:Item,Age:5996,Motion:[0.0,0.0,-0.1]}}}}}}}}}}}}}}}}}}}}}}}}}}}'

这是一个很大的差异，它让我无法使用它。 有任何已知的解决方法吗？

你的代码可以工作。这是prompt这会破坏结果。看看fiddle 。我将结果分配给 <textarea>您可以在哪里复制它
