unterminated string literal error in salesforce

问题

I am trying to get a value from salesforce class into a javascript variable. I am able to get the value if its a single line value, but if its multiline textarea it gives a unterminated string literal error

caseUpdate.Description = "{!ac__c.C_Info__c}";

After googling for sometime i came to know we can have a workaround for this by having a hidden field and using DOM storing it using the document.getElement.Id. But i am calling this code on a button click so i would not be able to create a input text or hidden field value. Any body who can provide an way to do it?

Thanks Prady

It is because of line breaks. merge fields are rendered unescaped into the output stream meaning that CRLFs push into a new line and break javascript strings. Either use the div/input trick or use Apex to replace \r\n's in the field with <br/> or whatever best suits the purpose. Also keep in mind that " will also terminate your JS string.

The easiest way is to just include a function in your extension and then you can use it across board

public String FixNewLine(String s) {
    if (s != null) return s.replaceAll('\r\n', '<br/>').replaceAll('"', '\\"');
    return null;
}

You should just be able to use the standard Salesforce JSENCODE() function if you are using OnClick Javascript in a button. This will escape any characters for you.

See the documentation.

I had the same issue but was able to fix it! The trick is the JSENCODE function. Its basically {!JSENCODE(Obj.Field)}"; So you are replacing your merge field with this function and nesting the merge field itself within the function. In my scenario I ended up with opptyObj.Description="{!JSENCODE(Case.Description)}"; as my total syntax. First calling upon my set object and field, and then the merge data to populate it.
