SyntaxError: missing ; before statement

Answer 1

Read this answer.

Here is an example:

'<input type="button" onClick="gotoNode(\'' + result.name + '\')" />'

In your case, you probably want to pass edit as a string, so change this

product_row +='<td><input type="text" name="edit_product_type" 
id="edit_product_type_'+this.id_sale_order+'" value="'+this.product_type+'" 
onblur="updateProduct(\'' + this.id_sale_order + '\','edit');" rel="edit" />';

to this

product_row +='<td><input type="text" name="edit_product_type" 
id="edit_product_type_'+this.id_sale_order+'" value="'+this.product_type+'" 
onblur="updateProduct(\'' + this.id_sale_order + '\',\'edit\');" rel="edit" />';

where the escape backslashes were used.

Answer 2

Check for typos:

either: onblur="updateProduct(\'' + this.id_sale_order + '\',\''+edit+'\');"

or: onblur="updateProduct(\'' + this.id_sale_order + '\',\'edit\');"

depends if edit is meant as variable name or string

Answer 3

You need to type correct single quotes in onblur function like,

onblur="updateProduct(\"' + this.id_sale_order + '\",\"edit\");" rel="edit" />

You can use both single and double quotes but make sure you have done them with care

Answer 4

You are missing quotes

    product_row +='<td><input type="text" name="edit_product_type" 
id="edit_product_type_'
+this.id_sale_order
+'" value="'
+this.product_type
+'" onblur="updateProduct(\'' 
+ this.id_sale_order 
+ '\',\'edit\');" rel="edit" />';

Answer 5

If you break down your code you will find the problem at second last row where if you remove the word 'edit' you will not get an error and if you put it in double quotation marks you won't get an error but if you put it in single quotation mark , you will get error

product_row +='<td><input type="text" 
name="edit_product_type" 
id="edit_product_type_'+this.id_sale_order+'"
value="'+this.product_type+'" 
onblur="updateProduct(\'' + this.id_sale_order + '\',

\'edit\');" // the problem is here , so put on 'edit' with \'edit\'

rel="edit" />';
