Currently, I am using JavaScript to read a hidden field value. However, the value I am obtaining is wrapped within single quotes ('78963'). How can I eliminate this single quote and retrieve the value without it (78963)? Any assistance in resolving this issue would be greatly appreciated.
If you need to convert a string value to a numeric value, there are a few ways to do it.
One option is to use the parseInt() function:
parseInt("78963", 10); // 78963
If the value includes decimals, you can use the parseFloat() method:
parseFloat("78963.1"); // 78963.1
Another shortcut is to simply add a plus sign before the string:
+"78963"; // 78963
If you just need to remove single quotes from a string, you can use the replace() method:
"'78963'".replace(/'/g, ""); // "78963"
Alternatively, you can split the string using single quotes and access the value at index 1:
"'78963'".split("'")[1]; // "78963"
The .replace() function for manipulating strings can be found at this link: http://www.w3schools.com/jsref/jsref_replace.asp
Extracting a substring by omitting the first and last characters of a string using the substr() method.
To retrieve the precise value, simply use the code $('#element').val(). Ensure that 'element' refers to the unique identifier of the hidden box.
In the case that the hidden input field is found to have single quotes, the optimal solution (in my view) is the suggestion provided by JamesAllardice in a comment:
yourValue.replace(/'/g, "");
