将数据 json 字符串传递给数字 Vue.js

Question

我正在尝试按数字和通过 API 收集的单词对表格进行排序，单词对它们进行了很好的排序，但数字没有，如何将字符串的值传递给数字。

这是我给 API 打的电话。

 axios.get(`/json/secciones`+ tienda +`.json`).then(response => {this.userInfo = response.data;}).catch(e => {this.errors.push(e);});

并把它还给我

 [ { "id_store": 2, "id_section": 1, "desc_section": "MATERIALES DE CONSTRUCCION", "id_rule": 1, "sale_potential": "79413.5525190617" }, { "id_store": 2, "id_section": 2, "desc_section": "CARPINTERIA Y MADERA", "id_rule": 1, "sale_potential": "74704.3439572555" }, { "id_store": 2, "id_section": 3, "desc_section": "ELECTR-FONTAN-CALOR", "id_rule": 1, "sale_potential": "101255.89182774" }, { "id_store": 2, "id_section": 4, "desc_section": "HERRAMIENTA", "id_rule": 1, "sale_potential": "36969.8901028374" } ]

我怎么能像这样找回它？

 [ { "id_store": 2, "id_section": 1, "desc_section": "MATERIALES DE CONSTRUCCION", "id_rule": 1, "sale_potential": 79413.5525190617 }, { "id_store": 2, "id_section": 2, "desc_section": "CARPINTERIA Y MADERA", "id_rule": 1, "sale_potential": 74704.3439572555 }, { "id_store": 2, "id_section": 3, "desc_section": "ELECTR-FONTAN-CALOR", "id_rule": 1, "sale_potential": 101255.89182774 }, { "id_store": 2, "id_section": 4, "desc_section": "HERRAMIENTA", "id_rule": 1, "sale_potential": 36969.8901028374 } ]

Answer 1

尝试使用map function 应用于数组并使用Number() object 构造函数将该属性转换为数字：

axios.get(`/json/secciones`+ tienda +`.json`)
      .then(response => {this.userInfo = response.data.map(item=>{
                                     item.sale_potential=Number(item.sale_potential)
                                          return item;
                                      });

})
      .catch(e => {this.errors.push(e);});
