书签打开多个URL无效 [英] Bookmarklet to open multiple urls not working

问题描述

我一直在研究以下内容一段时间.我认为应该可以...但是不会.我知道我必须在运行它的任何页面上禁用Chromes adblock，但是我看不到我在哪里出错了.它的预期用途是突出显示文本，然后运行书签，它将在URL末尾使用该文本打开4个URL.任何帮助是极大的赞赏.'''

  s = document.selection?document.selection.createRange().text:window.getSelection?window.getSelection().toString():document.getSelection?document.getSelection():'';如果(s ==''){s = prompt(``您％20did％20not％20not％20select％20any％20text％20to％20search％20for.％20Enter％20the％20text％20to％20search％20for％20for'20，'，'');}如果{window.open("https://www.google.com/" + s);setTimeout(function(){window.open('https://youtube.com/'+s，"_blank");}，3000)；setTimeout(function(){window.open('https://url3.com/'+s，"_blank");}，9000)；setTimeout(function(){window.open('https://url4.com/'+s，"_blank");}，12000)；}; 

新文本Document.txt用新的windows.txt显示.'''

解决方案

因此，检索所选文本的一般方法是 window.getSelection().toString();

您似乎自己已经做到了.但是，似乎您的第三行在提示和开括号之后紧跟了一个错误类型，一个额外的单引号；修复后，代码开始工作.

无论如何，有几个更多调整可以使代码更好:

• 将文本提示为纯文本，不转义空格等.
• 最好不要使用全局变量，例如 s ；因此，最好至少具有 var s .
• 位格式( = 后的空格，到处都是单引号，而不是双引号来组成统一的代码)

修改版本:

  var s = document.selection?document.selection.createRange().text:window.getSelection?window.getSelection().toString():document.getSelection?document.getSelection():'';if(s ==''){s =提示(您没有选择要搜索的任何文本.请输入要搜索的文本."，'');}如果{window.open('https://www.google.com/'+s);setTimeout(function(){window.open('https://youtube.com/'+s,'_blank');}，3000)；setTimeout(function(){window.open('https://url3.com/'+s,'_blank');}，9000)；setTimeout(function(){window.open('https://url4.com/'+s,'_blank');}，12000)；}; 

而且，顺便说一句，如果要将其作为小标签(如标签中的标签)，则您的代码应位于其中，并另存为小书签(浏览器用JS代码添加书签):

  javascript:(function(){/*上面的代码*/})(); 

ive been working on the below for a while. It should work i think... but wont. i know i will have to disable chromes adblock on whatever page i run it on but i cant see where ive gone wrong. Its intended use is to highlight text then run bookmarklet which will open 4 urls using that text at the end of the url. any help is greatly appreciated. '''

解决方案

So in a general way of retrieving selected text is window.getSelection().toString();

It looks like you have almost made it yourself. However, it seems like your third line has a minor mistype, an extra single quotation mark, right after prompt and an opening bracket; after the fix the code starts working.

Anyway, several more tweaks to make the code even better:

• Prompt text as plain text, without escaping spaces etc.
• It is better not to use global variables, like s; therefore, it might be better to have at least var s.
• A bit formatting (spaces after =, single quotation marks everywhere instead of double quotes to make uniform code)

A modified version:

var s = document.selection?document.selection.createRange().text:window.getSelection?window.getSelection().toString():document.getSelection?document.getSelection():'';
if(s == ''){
    s = prompt('You did not select any text to search. Enter the text to search for.','');
}
if(s)
{ 
    window.open('https://www.google.com/'+s);   
    setTimeout(function(){
        window.open('https://youtube.com/'+s,'_blank');
    }, 3000);
    setTimeout(function(){
        window.open('https://url3.com/'+s,'_blank');
    }, 9000);
    setTimeout(function(){
        window.open('https://url4.com/'+s,'_blank');
    }, 12000);
};

And, by the way, if you want to make it as a bookmarklet, as it is in your tag, then your code should be inside this and saved as a bookmarklet (a browser bookmark with js-code):

javascript:(function () {
    /*code above here*/
})();
