jquery bulk modifies the name value, adding the name suffix in bulk, not each (no loops required)

Background

form fields, configuring the Where property to automatically refresh to the Queryable area, query fields need to add _where suffix, response background rules

Problem

Batch set query field, you must increase the _where suffix in bulk to normal query. Each loop is a bit cumbersome, there is no more convenient batch modification method.

Investigation

The direction is jquery batch modification name, the entire internet is flooded with. attr ("name", "New_value"). Only single-value modifications, eventually, found this systematic article

Jquery attr () method property assignment and property acquisition

jquery uses the attr () method to get and set element properties, attr is the abbreviation for attribute (attribute), which is often used in jquery DOM operations to attr (), and attr () has 4 expressions.

1. attr ( attribute name ) //Get the value of the property (Gets the property value of the first matching element. This method makes it easy to get the value of an attribute from the first matching element. Returns undefined if the element does not have a corresponding attribute)

2. attr ( property name, property value ) //Set the value of the property (set a property value for all matching elements.) ）

3. attr ( attribute name , function value ) //Set the function value of the property (set a computed property value for all matching elements.) Instead of providing a value, you provide a function that is evaluated by the function as the value of the property. ）

4.attr (properties) //Set multiple attribute values for the specified element: {attribute name one: attribute value one, property name two: "Property value Two", ...}. (This is the best way to set many properties in bulk in all matching elements.) Note that if you want to set the class property of an object, you must use ' className ' as the property name. Or you can use ' class ' or ' id ' directly. )

Reference

Scheme

The use of the program is 3rd, the source code is as follows

Note the function form of scenario 3rd, which is the code $ ("Input[where]") for Each loop. attr ("name", function () {return this.name+ "_where"});

Summarize

Perfect solution, skip each loop code block and look at the tall
