如何使用 Javascript 将 HTML 表特定文本值转换为 href 链接( 标记)?
在我的 Flask 应用程序的主页上,我有一个 HTML 表,其最后一列值可以是文本,其模式化如下:
我现在尝试使用 JavaScript 通过 href 链接转换 HTML 表中的所有“编辑问题”值,一旦我单击此链接即可访问另一个 HTML 页面。为此,我循环 HTML 表中的每一行并将 HTML 链接放入单元格内。不幸的是,当我运行下面的代码时,我收到源映射错误:
请在下面找到我的 JS 代码:
function convert_cellTable(){
let table=document.getElementsByTagName("table").value;
let row, rows = table.rows;
let cell, cells;
// For each row in the table
for (var i=0, iLen=rows.length; i<iLen; i++) {
row = rows[i];
cells = row.cells;
// Identify in each cell if the text content equal to "Edit Issue"
for (var j=0, jLen=cells.length; j<jLen; j++) {
cell = cells[j];
let TextToConvert = "Edit Issue"
if (cells[j].textContent == TextToConvert) {
// cell text is replaced by an HTML link
cell[j].innerHTML = "<a href='updateform.html'>Edit Issue</a>";
}
}
}
}
您能否为我提供指导来更正上面的代码。谢谢
On the homepage of my Flask application, I have an HTML table whose last column values can be text which can be schematized as follows:
I am now trying to use JavaScript to convert all the "Edit Issue" values in the HTML table by an href link that would allow me once I click on this link to access another HTML page. For doing this, I loop every row in the HTML table and put HTML link inside cell. Unfortunately, when I run the code below, I get a source map error:
Please find below my JS code:
function convert_cellTable(){
let table=document.getElementsByTagName("table").value;
let row, rows = table.rows;
let cell, cells;
// For each row in the table
for (var i=0, iLen=rows.length; i<iLen; i++) {
row = rows[i];
cells = row.cells;
// Identify in each cell if the text content equal to "Edit Issue"
for (var j=0, jLen=cells.length; j<jLen; j++) {
cell = cells[j];
let TextToConvert = "Edit Issue"
if (cells[j].textContent == TextToConvert) {
// cell text is replaced by an HTML link
cell[j].innerHTML = "<a href='updateform.html'>Edit Issue</a>";
}
}
}
}
Could you please provide me guidelines to correct the code above. Thanks

如果列数已知或固定,您可以选择最后一列的所有
td
元素,然后循环遍历这些元素以相应地更新innerHTML
。If the number of columns is known or is fixed, you could select all of the last column
td
elements, then loop through those to update theinnerHTML
accordingly.
