javascript - 页面刷新时未重置Localstorage值

用户从选择框中选择的值设置为按钮值，但它的（LocalStorage）值在页面刷新时更改（F5）

function change(){
        var opt = $("#gsb_tb option:selected").text();
        var stored =  localStorage.setItem('project',JSON.stringify(opt));
        var valueofstore= JSON.parse(localStorage.getItem('project'));
        document.getElementById("set-project").value= valueofstore;
    }

<select id="gsb_tb" style="height: 45px; width: 78%; margin-left: 70px; padding-right: 90px; vertical-align: middle;" tabindex="0" autocomplete="off">
<option value="" disabled selected>Select your Project</option>
<option value="370"> E-Card</option>
<option value="278">Labs</option>
<option value="196">Absolute DB</option>

<input value="Set as Working Project" onclick="change()" aria-label="I'm Feeling Lucky" name="btnI" class='center-btn' jsaction="sf.lck" type="submit" id='set-project'>

最佳答案

据我了解，您可能正在寻找window.onload

function change(){
    var opt = $("#gsb_tb option:selected").text();
    var stored =  localStorage.setItem('project',JSON.stringify(opt));
    var valueofstore= JSON.parse(localStorage.getItem('project'));
    console.log(valueofstore)
    document.getElementById("set-project").value= valueofstore;
}
function load(){
    var valueofstore= JSON.parse(localStorage.getItem('project'));
    console.log(valueofstore)
    if (valueofstore){
        document.getElementById("set-project").value= valueofstore;
    }
}
window.onload = load;
