info.search=$(this).text().trim();

As an AI language model, I do not have the context to fully understand what this line of code is trying to achieve. However, based on my programming knowledge, it seems like this line of code is assigning the trimmed text value of the current element to the variable "info.search".
Here's a breakdown of the code:
- $(this) refers to the current element being processed in the code.
- .text() is a jQuery method that retrieves the text content of the element.
- .trim() is a JavaScript method that removes any whitespace from the beginning and end of the string.
- The resulting value is then assigned to the variable "info.search".

let data = []; // 搜索的数据 const searchInput = document.getElementById("search"); const searchResult = document.getElementById("search-result"); // 从数据文本中解析出搜索数据 fetch("data.txt") .then((response) => response.text()) .then((text) => { data = text.split("\n").filter((item) => item.trim() !== ""); }) .catch((error) => console.error(error)); searchInput.addEventListener("input", (event) => { const keyword = event.target.value.trim(); // 获取输入框中的值并去除首尾空格 if (!keyword) { searchResult.innerHTML = ""; // 关键词为空,清空下拉列表 return; } const matchedData = data.filter((item) => item.includes(keyword) ); // 过滤出匹配的数据 if (matchedData.length === 0) { searchResult.innerHTML = "<li>无匹配结果</li>"; // 没有匹配的数据 } else { searchResult.innerHTML = matchedData .map((item) => `<li>${item}</li>`) .join(""); // 根据匹配的数据渲染下拉列表 } }); searchResult.addEventListener("click", (event) => { if (event.target.tagName === "LI") { searchInput.value = event.target.innerText; searchResult.innerHTML = ""; // 选中下拉列表中的内容,清空下拉列表 } }); 将这段内容中的数据解析换一种写法,其中能够正常解析出文本数据
可以将获取数据的部分改为使用XMLHttpRequest对象进行异步请求,如下所示:
```javascript
let data = []; // 搜索的数据
const searchInput = document.getElementById("search");
const searchResult = document.getElementById("search-result");
// 从数据文本中解析出搜索数据
const xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
if (this.readyState === 4 && this.status === 200) {
data = this.responseText.split("\n").filter((item) => item.trim() !== "");
}
};
xhr.open("GET", "data.txt");
xhr.send();
searchInput.addEventListener("input", (event) => {
const keyword = event.target.value.trim(); // 获取输入框中的值并去除首尾空格
if (!keyword) {
searchResult.innerHTML = ""; // 关键词为空,清空下拉列表
return;
}
const matchedData = data.filter((item) =>
item.includes(keyword)
); // 过滤出匹配的数据
if (matchedData.length === 0) {
searchResult.innerHTML = "<li>无匹配结果</li>"; // 没有匹配的数据
} else {
searchResult.innerHTML = matchedData
.map((item) => `<li>${item}</li>`)
.join(""); // 根据匹配的数据渲染下拉列表
}
});
searchResult.addEventListener("click", (event) => {
if (event.target.tagName === "LI") {
searchInput.value = event.target.innerText;
searchResult.innerHTML = ""; // 选中下拉列表中的内容,清空下拉列表
}
});
```
这里使用XMLHttpRequest对象对data.txt进行异步请求,当请求成功后,将返回的文本数据解析为数组并赋值给data变量。
<template> <div> <input type="text" v-model="searchId" placeholder="请输入sample_id"> <button @click="search">搜索</button> <el-table ref="multipleTable" :data="filteredData" tooltip-effect="dark" style="width: 100%" @selection-change="handleSelectionChange"> <el-table-column type="selection" width="55"></el-table-column> <el-table-column prop="sample_id" label="sample_id" width="120"> <template slot-scope="scope">{{ scope.row.sample_id }}</template> </el-table-column> <el-table-column prop="feature0" label="feature0" width="120"></el-table-column> <el-table-column prop="feature1" label="feature1" width="120"></el-table-column> <el-table-column prop="feature2" label="feature2" width="120"></el-table-column> <el-table-column label="操作" fixed="right" width="135"> <template slot-scope="scope"> <el-button type="text" @click=handleEdit(scope.$index)>编辑</el-button> <el-button type="text" @click="deleteRow(scope.$index)">删除</el-button> </template> </el-table-column> </el-table> </div> </template> <script> export default { data() { return { searchId: '', tableData: [], // your table data array filteredData: [] // array to store filtered data } }, methods: { search() { if (this.searchId.trim() === '') { this.filteredData = this.tableData; // if searchId is empty, show all data } else { this.filteredData = this.tableData.filter(item => { return String(item.sample_id).includes(this.searchId); }); } } } } 实现根据sample_id的值进行查询,并将结果展示到表格中
你的代码看起来已经正确地实现了根据 `sample_id` 的值进行查询,并将结果展示到表格中。当你在输入框中输入 `sample_id` 的值并点击搜索按钮时,表格会根据 `sample_id` 进行过滤,并将匹配的数据展示出来。
请确保你的 `tableData` 数组包含正确的数据,并且在点击搜索按钮时能够正确地更新 `filteredData` 数组。
