How to find similarities between a text string and an array?-CodePudding

I have a string array, which I want to compare with a text string, if it finds similarities I want to be able to mark in black the similarity found within the string

example:

context.body: 'G-22-6-04136 - PatientName1'

newBody: ['G-22-6-04136 - PatientName1' , 'G-22-6-04137 - PatientName2']

When finding the similarity between the two the result would be something like this

newBody: [**'G-22-6-04136 - PatientName1'** , 'G-22-6-04137 - PatientName2']

How could I do it? Is this possible to do? In advance thank you very much for the help

const totalSize: number = this.getSizeFromAttachments(attachments);
const chunkSplit = Math.floor(isNaN(totalSize) ? 1 : totalSize / this.LIMIT_ATTACHMENTS)   1; 
const attachmentsChunk: any[][] = _.chunk(attachments, chunkSplit);

if ((totalSize > this.LIMIT_ATTACHMENTS) && attachmentsChunk?.length >= 1) {
   
    const result = attachment.map(element => this.getCantidad.find(y => element.content === y.content))
            const aux = this.namePatient
            const ans = [] 
            result.forEach(ele => {
              const expected_key = ele["correlative_soli"];
              if (aux[expected_key]) {
                const newItem = { ...ele };
                newItem["name_Patient"] = aux[expected_key]
                newItem["fileName"] = `${expected_key}${aux[expected_key] ? ' - '   aux[expected_key] : null}\n`.replace(/\n/g, '<br />')
                ans.push(newItem)
              }
            });
            
            let newBody: any;
            const resultFilter = attachment.map(element => element.content);

            const newArr = [];
            ans.filter(element => {
              if (resultFilter.includes(element.content)) {
                newArr.push({
                  fileNameC: element.fileName
                })
              }
            })

            newBody = `• ${newArr.map(element => element.fileNameC)}`;

            const date = this.cleanDateSolic;
            const amoung= attachmentsChunk?.length;
            const getCurrent = `(${index}/${attachmentsChunk?.length})`
            const header = `${this.cleanDateSolic} pront ${attachmentsChunk?.length} mail. This is the (${index}/${attachmentsChunk?.length})`;

            console.log('body', context.body);
   
           // context.body is the body I receive of frontend like a string

            const newContext = {
              newDate: date,
              amoung: amoung,
              getCurrent: getCurrent,
              newBody: newBody,
              ...context
            }
 
            return this.prepareEmail({
              to: to,
              subject: ` ${subject} (Correo ${index}/${attachmentsChunk?.length})`,
              template: template,
              context: newContext,
            }, attachment);
 
}

Based on your example, it looks like the string needs to be an exact match, is that correct?

Also, "mark it in bold" is going to depend on what you're using to render this, but if you just want to wrap the string in ** or <b> or whatever, you could do something like this:

newBody.map(str => str === context.body ? `**${str}**` : str);

CodePudding user response：

You can just see if string exists in the array by doing if arr.includes(desiredStr) //make text bold
