使用jQuery从文本区域搜索单词

[英]search words from text area using jquery

 原文  2015-10-03 08:13:09  4   1    javascript/ jquery/ html/ ajax

问题描述

I am trying to search some words in a textarea. 我正在尝试在文本区域中搜索一些单词。 These words are taken from different textboxes. 这些词取自不同的文本框。 It is working fine but when I search words which have some common name like(nokia lumia and nokia lumia 310) then it is not giving me perfect result. 它工作正常，但是当我搜索具有某些常用名称的单词（如nokia lumia和nokia lumia 310）时，它并没有给我完美的结果。 I want to search complete sentence and then lock that sentence, so that it won`t be used in other searches. 我想搜索完整的句子，然后锁定该句子，这样它就不会在其他搜索中使用。

在此处输入图片说明

In this picture we have multiple words to be searched, but only few of them, not the whole sentence. 在这张图片中，我们有多个单词要搜索，但是只有几个单词而不是整个句子。

I havent used the jquery highlighter plugin but on order to iterate over a regex per sentence you can do something like this with a while loop. 我还没有使用jQuery荧光笔插件，但是为了迭代每个句子的正则表达式，您可以使用while循环执行类似的操作。 You have to turn off use strict. 您必须关闭使用严格。 

Var mystr = 'textarea text etc. ..';
 Var reg = RegExp='(^|\\.)([^\\.]*' + '(' + 'nokia' + '|' '    whatever' + '))+', 'g');
While(each = reg.exec(mystr)){
    Var sentence = each[0];
   // use the index position of the reg to relate to the position in the textarea
Console.log(reg.lastIndex);



}
