I am trying to use JavaScript to get the value from an HTML text box but value is not coming after white space

I only get: "software" from the above.

How do I get the full value: "software engineer"?

Answer 1

Your element does not have an ID but just a name.

(您的元素没有ID，只有一个名称。)

So you could either use getElementsByName() method to get a list of all elements with this name:

(因此，您可以使用getElementsByName()方法获取具有此名称的所有元素的列表：)

var jobValue = document.getElementsByName('txtJob')[0].value  // first element in DOM  (index 0) with name="txtJob"

Or you assign an ID to the element:

(或者您为元素分配ID：)

<input type="text" name="txtJob" id="txtJob" value="software engineer">
