javascript function on click not working [closed]

I have a function which prints bar code and I want to make a click event, but when I am calling my function using javascript on click, its not working, please find the code below? I am able to view it on page without onclick. I want to call get_object(id)

If you copy-pasted it, you first need to change

onclick "get_object("110091")"

To

onclick="get_object('110091')"

You forgot the = sign, and you can not use double quotes " inside an attribute value (since they are already used for separating it)

---

your missing the = sign it should be onclick="get..."

---

Is your post mistyped, or is the "=" after "onclick" actually missing? Also, you should use single-quote inside the get_object() method, or this will not properly parse.

---

Your tag needs to read:

... onclick="get_object('110091')" ...

note both the equals sign, and using the alternate quote characters inside - as it is your use of double quotes both to enclose the attribute and to pass the function parameter will break.

Also, why use such a complicated get_object() function? Your question is tagged HTML5 which AFAIK guarantees that getElementById() will be available.

---

Your get_object function does nothing but return the DOM object using the id passed in - it doesn't draw any barcodes... It sounds to me like you want:

<button type="button" button data-theme="b" id="submit" onclick="DrawCode39Barcode(get_object('inputdata').innerHTML,0);return false;">theater</button>
