使用 Excel VBA 从 javascript 中的文本框中获取值

Question

I have a problem with a Macro in Excel, I want to return the value of an "input type="text"" in a javascript webpage, but the value isn't specified in the code (value=""), and it never changes, even when the webpage shows a text in the textbox (The webpage "prints" a text in this textbox, it's not an input by the user).

Using "IE.Document.getElementById("lat_txt_velmaxima").Value", returns Null.

The code on the page is:

class="campo txt_velmaxima"> <label for="lat_txt_velmaxima">Velocidade máxima:</label> 

<input type="text" name="lat_txt_velmaxima" id="lat_txt_velmaxima"
disabled="disabled" value="" readonly="readonly" />

Answer 1

If I'm understanding your question correctly, you just need to grab the value of that readonly text input.

If that's the case, the right way to query the DOM API through JavaScript is the following:

document.getElementById('lat_txt_velmaxima').value;

Note the lowercase d in document , and lowercase v in value .
