将数组中的字符串更改为对象

Question

我试图弄清楚如何将字符串更改为对象。然后，我要获取该对象并将其插入数组，还要从数组中删除字符串。有关如何执行此操作的任何想法？到目前为止，我通过数组获取映射的字符串。

searchTerms.map(term => {
            if(term.length > 25) {
                const trimmedSearchTerm = term.substring(0,25) + '...';
                const obj = {
                    value: term,
                    trimmedValue: trimmedSearchTerm,
                    icon: 'search',
                    removable: true,
                };
                return searchTerms.push(obj);
                
            } else if(term === "Last 500"){
                const obj = {
                    value: term,
                    trimmedValue: term,
                    icon: 'date_range',
                    removable: false,
                }
                return searchTerms.push(obj)
            } else {
                term = {
                    value: term,
                    trimmedValue: term,
                    icon: 'search',
                    removable: true,
                }
            }
        });

我相信您只是忘了返回每个条件的值。这是一个有效的例子

let searchTerms = ["test1", "1234567891011121314151617181920", "Last 500"]

const mappedTerms = searchTerms.map(term => {
    let mappedTerm;
    if(term.length > 25) {
        const trimmedSearchTerm = term.substring(0,25) + '...';
        mappedTerm = {
            value: term,
            trimmedValue: trimmedSearchTerm,
            icon: 'search',
            removable: true,
        };
    } else if(term === "Last 500"){
        mappedTerm = {
            value: term,
            trimmedValue: term,
            icon: 'date_range',
            removable: false,
        }
    } else {
        mappedTerm = {
            value: term,
            trimmedValue: term,
            icon: 'search',
            removable: true,
        }
    }
    
    return mappedTerm;
});

console.log(mappedTerms);
