<div align="center"><input type="text" id="input_search"> <button id="button_search">搜索</button></div>var db;button_search.onclick = function() { search(); }input_search.onkeypress = function(e) {if (e.keyCode == 13)search();
}var request = window.indexedDB.open("MyTestDatabase", 1);
request.onsuccess = function(event){db = event.target.result;input_search.value = '';search();
};function search() {table.innerHTML = '';var i = 1;var tr = document.createElement('tr');var th = document.createElement('th');th.textContent = 'id';tr.append(th);th = document.createElement('th');th.textContent = 'name';tr.append(th);th = document.createElement('th');th.textContent = 'age';tr.append(th);th = document.createElement('th');th.textContent = 'email';tr.append(th);table.append(tr);var objectStore = db.transaction("customers").objectStore("customers");var request = objectStore.openCursor();request.onsuccess = function(event){var cursor = event.target.result;if (cursor) {var s = input_search.value.toLowerCase(); if (cursor.value.name.includes(s) || cursor.value.age.toString().includes(s) || cursor.value.email.includes(s)) {tr = document.createElement('tr');var td = document.createElement('td');td.textContent = i;tr.append(td);td = document.createElement('td');td.textContent = cursor.value.name;tr.append(td);td = document.createElement('td');td.textContent = cursor.value.age;tr.append(td);td = document.createElement('td');td.textContent = cursor.value.email;tr.append(td);table.append(tr);i++;}cursor.continue();} else {console.log('No more cursor !');}};
}我这样过滤还不如直接用数组！
这篇关于IndexedDB查询的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
