我們在iOS UIWebView中嵌入了一些自定義HTML頁面。我們加載頁面的路徑,然後,所有的腳本都加載到頁面中,一切都很好。除一個之外的所有東西:按鈕的「啓用」狀態。雖然它在Chrome和Safari中100%工作,但一旦嵌入UIWebView,每次按下按鈕時似乎都不會刷新。但我點擊一個字段,然後綁定函數似乎被調用。我使用了Kendo documentation中指定的「啓用」綁定。iOS中的劍道MVVM UIWebView
*工作sample here。如果你使用Safari加載它在iPad上,你會看到這個問題
這裏是我的HTML樣本:
<div class="gui-header-section k-content">
<h1>Test</h1>
</div>
<div id="recolteInfoDiagnostic">
<div id="section1" data-bind="visible: isSectionVisible(1)">
<div class="gui-form-section k-content">
<div>
<form>
<ul class="fieldlist">
<li>
<label for="fname">First name</label>
<input id="fname" data-bind="value: firstNameSousc" class="k-textbox" /></li>
<li>
<label for="lname">Last Name:</label>
<input id="lname" data-bind="value: lastNameSousc" class="k-textbox" /></li>
<li>
<label>Gender:</label>
<select id="cbxGenderSousc" data-bind="source: gendersDataSource, value: genderSousc"></select></li>
<li>
<label for="agree">License Agreement</label>
<input type="checkbox" id="agree" data-bind="checked: agreed" />
I have read the licence agreement</li>
</ul>
</form>
</div>
</div>
<div class="gui-form-section k-content">
<div>
<!-- Some content, ommited for clarity -->
</div>
</div>
</div>
<div id="section2" data-bind="visible: isSectionVisible(2)">
<div class="gui-form-section k-content">
<!-- Some content, ommited for clarity -->
</div>
<div class="gui-form-section k-content">
<!-- Some content, ommited for clarity -->
</div>
</div>
<div id="navToolBar" class="gui-header-section k-content">
<div>
<button data-bind="enabled: isBackEnabled, click: back" class="k-button k-primary">Back</button>
<button data-bind="enabled: isNextEnabled, click: next" class="k-button k-primary">Next</button>
</div>
</div>
</div>
而且連同它的JavaScript:
$(document).ready(function() {
var kendoViewModel = kendo.observable({
formID: "informationsDiagnostic",
visibleSectionNo: 1,
totalPageNumber: 2,
firstNameSousc: "",
lastNameSousc: "",
genderSousc: "",
agreed: false,
gendersDataSource = new kendo.data.DataSource({
data: [
{ text: "Male", lang: "en", value: "M" },
{ text: "Female", lang: "en", value: "F" }
]
}),
isBackEnabled: function() {
return !(this.get("visibleSectionNo") === 1);
},
isNextEnabled: function() {
return !(this.get("visibleSectionNo") === this.get("totalPageNumber"));
},
next: function (e) {
e.preventDefault();
this.set("visibleSectionNo", this.get("visibleSectionNo") + 1);
},
back: function (e) {
e.preventDefault();
this.set("visibleSectionNo", this.get("visibleSectionNo") - 1);
},
isSectionVisible: function(pageNumber) {
return (pageNumber === this.get("visibleSectionNo"));
}
});
$("#cbxGenderSousc").kendoDropDownList({
dataSource: gendersDataSource,
dataValueField: "value",
dataTextField: "text"
}).data("kendoDropDownList");
kendo.bind($("#recolteInfoDiagnostic"), kendoViewModel);
});
請注意,「可見」屬性上的數據綁定工作正常,但我無法使其在「已啓用」屬性上正常工作。表單中的所有其他綁定都可以。
