访问“此”表单元格的值

Question

I have a form, after form has been filled and add button pressed - all the values from the form get to PouchDB and then into the table in the browser. I need to make an "edit" option. The idea is:

<td ondblclick='updateVaucher()' style='cursor: pointer'>"+data[i].doc.vaucherID+
                "</td>

Now the question is: how do I get the value of the cell (which is an ID) so that then I could download the rest of the information into the form?

I would like it to be something like that:

function updateVaucher(){
  var mydoc = this.td.value;
  ...
}

Answer 1

To get a reference to the element inside the function, you can pass the element to it from the event handler:

ondblclick='updateVaucher(this)'

You can get the content of an element via innerText or textContent (cross-browser):

function updateVaucher(ele){
  var mydoc = ele.textContent || ele.innerText;
  ...
}
