如何在JQuery中触发选择的事件（按键或模糊）

Question

$("#var").keypress(function (a) {
        //line 1
        //line 2
        if(condition) {
            functionToBecalled(params);
        }

    }).blur(function (a) {
        //line 1
        //line 2
        if(condition) {
            functionToBecalled(params);
        }
    });

#var is the text-field name. The function "functionToBecalled()" performs get operation using XHR in another file.Same statements are to be performed in both cases.

I want the data to be retrieved as the user presses enter or clicks outside the text-field.

You have a mistake in your code:

... }.blur( ...

should be

... }).blur( ...

since .keypress( ... ) is a function and you are chaining .blur after .keypress.
