Question

我在淘汰赛中有以下代码。 html是

<p id="inputField">
    What do you want to search?: 
    <input data-bind="
        textInput: searchLocation, 
        event: {focus:  focusHandler}"/>
</p>

viewModel是

function  NeighborhoodModel() {
    var self = this;

    self.focusHandler = function(){
        console.log("focus self.searchLocation "+searchLocation());
    };

    self.searchLocation= ko.observable("");
    searchLocation = ko.observable("");
    self.locations = ko.observableArray([]);
    self.nameLocation = ko.observable(" ");
    console.log(" begin model");
    console.log("model self.searchLocation "+searchLocation());

};

ko.applyBindings(new NeighborhoodModel());

如何恢复searchLocation的值？

控制台中的消息是

开始模特

project5.js：15 model self.searchLocation

project5.js：6焦点自我.searchLocation

您已经定义了两次searchLocation，一次是自我，之后是另一次。另外，您应该使用value绑定而不是textInput

看到这个更新的小提琴：http://jsfiddle.net/uete2Lsq/

<p id="inputField">
    What do you want to search?: 
    <input data-bind="
        value: searchLocation, 
        event: {focus:  focusHandler, blur: focusHandler}"/>
</p>
